**** Sorry I made a mistake at 00:49 I incorrectly label and describe the thigh adductors as hip abductors. The thigh adductors pull the legs together when they contract.*******

I cover many of the major muscles of the human body.
The Pectoralis major: is a thick, fan-shaped muscle, situated at the chest of the human body.
The Bicep is a large muscle that lies on the front of the upper arm between the shoulder and the elbow. Its main function is to flexes and twists the forearm.

The abdominal muscles support the trunk, allow movement and hold organs in place

The sartorius muscle is the longest muscle in the human body. It is a long, thin, superficial muscle that runs down the length of the thigh This muscle helps you cross your legs

The abductor muscle group is located on the lateral side of the thigh and moves the thigh away from the body’s midline.

The trapezius muscle resembles a trapezoid or diamond-shaped quadrilateral
It helps support the weight of the arm and move the shoulder

The Deltoid forms the rounded contour of the human shoulder. It is a prime mover of arm

The latissimus dorsi is the largest muscle in the upper body.It is responsible for extension, adduction, internal rotation of the shoulder. This muscle helps you do pull ups at the gym.

The serratus anterior is a muscle that originates on the surface of the 1st to 8th ribs at the side of the chest. It acts to pull the scapula forward around the thorax.

External oblique The external oblique functions to pull the chest downwards and compress the abdominal cavity, It also performs (same side) side-bending and (opposite side) rotation

The brachioradialis is a muscle of the forearm that flexes the forearm at the elbow. For example, using a hammer.

Finger extensions include 9 extensor muscles found in the posterior side of the forearm and extend the hand and fingers.

Finger flexors help you close your hand

Quadriceps is a large muscle group that includes the four prevailing muscles on the front of the thigh. These muscles are the great extensor muscle of the knee

Hamstrings a hamstring is one of the three posterior thigh muscles in between the hip and the knee The hamstrings cross and act upon two joints – the hip and the knee

The gastrocnemius forms half of the calf muscle. Its function is flexing the foot at the ankle joint and flexes the leg at the knee joint.

Tibialis anterior It is responsible for flexing the foot backward and inverting the foot.

The soleus is a powerful muscle in the back part of the lower leg aka (the calf). It runs from just below the knee to the heel, and is involved in standing and walking.

The infraspinatus muscle is a thick triangular muscle It is one of the four muscles of the rotator cuff, it’s main function is to rotate the humerus and stabilize the shoulder joint.

The teres major helps rotate the humerus and assists the latissimus dorsi in drawing the previously raised humerus downwards and backward.

Triceps is a large muscle on the back of the upper arm It is responsible for straightening the arm.

The gluteus medius is a muscle that helps with hip movement

When you walk and run it aids in stabilizing your pelvis, in particular when you perform activities where you balance on a single leg.

Gluteus maximus is the main extensor muscle of the hip You use the gluteus maximus when you stand up from a chair, sprint, run, and go up steps.

Correction:
0:49 Sorry I made a mistake. The muscles in dark blue, labeled as “abductors”, are in fact the “Adductor” group. They are the muscles that draw your legs toward the midline and assist with medial rotation also known as crossing your legs.

The deciduous forest biome is known for having four seasons and trees that drop their leaves in the winter.
This biome is located in the eastern half of the United States, Canada, Europe, parts of Russia, China, and Japan.
The deciduous forest has moderate winters and warm summers. It receives around 50 inches of rain a year. This rainfall allows trees like oak, maple, and beech trees to grow in this forest.
You will find bear,fox, and deer in this biome

X linked chromosomes explained,Humans have 23 pairs of chromosomes. One pair determine the gender of the child.A female will have xx chromosomes and males will have an x and a y chromosome
The x and y chromosomes not only carry the genes that determine male and female traits but also some other characteristics as well.
Since only men inherit Y chromosomes, they are the only ones to inherit Y-linked traits. The y chromosome carries around 200 genes.
There are about 1,100 human X-linked genes.
Most of them code for something other than female anatomical traits. Some X-linked genes are responsible for abnormal conditions such as hemophilia, red-green color blindness,
and "male pattern baldness".

Learn the difference between an observation and an inference. An observations uses our 5 senses to make observations. These observations can be qualitative or quantitative.
An inference is an explanation of the observation based on prior experience.

A surface wave is a wave in which particles of the medium undergo circular motion. Surface waves are neither longitudinal pause nor transverse. Pause Kinda like a liger
In longitudinal waves, the particles move parallel to the disturbance, and transverse waves the particles perpendicular relative to the direction of the disturbance. In a surface wave, it is only the particles at the surface of the medium that undergo the circular motion. The motion is both at right angles and parallels when the particles travel in a circle.

The circular motion of particles tends to decrease as you move further from the surface.

Large bodies of water like the ocean contain surface waves.

During an earthquake, Rayleigh waves are produced and are a type of surface wave that travels near the surface of solids. The circular motion of the medium near the surface produce both longitudinal and transverse motions

Your metabolism is the sum of all chemical reactions in your body.

Sir Isaac Newton—who lived in the 1600’s developed 3 laws to describe all states of motion.
Law 1 or the law of Inertia states that matter wants to resist any change in motion.
A. If an object is at rest, it wants to stay at rest.
B. If an object in motion wants to stay in motion.
C. The more mass an object has, the greater the inertia it has.

These dominoes will stay at rest forever unless an outside force acts on it like this push from someones hand
D.Let’s see this law in action After the player punts the ball, due to inertia, what does the ball want to keep doing? ___Go in motion_______________________________ Why doesn’t it? ______________
__Air friction gravity other forces act on it
In order for an object to change its motion, what must happen?

Why is the car hard to push?
The car wants to stay at rest and has a larger mass than the man trying to push it.

Law 2

Based on these observations, Newton came up with a law to describe acceleration.
Newton’s 2nd Law: “The acceleration of an object depends on the force acting on it and the mass of the object

There is an equation associated with this law:

F= ma
Force = mass multiplied by acceleration

Look at this golf swing
The golf club has a high rate of acceleration and strikes the golf ball with great force

The hammer has a greater mass and acceleration than the piggy bank

Law Three

Newton’s 3rd Law of Motion --“For every action, there is an equal and opposite reaction

Look closely at this jellyfish swimming
He moves his body backward but moves forward because the water exerts a force in the opposite direction which moves the jellyfish forward

Same with the skateboard
The foot is pushing backward but the skateboard is going forward

Malleability and Ductility-- Malleability and Ductility
Malleability is the ability of an object to be hammered into shapes.
Most metals are malleable.
Copper, gold, and silver are very malleable.
Ductility is the ability of an object to be stretched into wires.
Ductility and malleability are physical properties.

In this video, I explain balanced and unbalanced forces from a physics viewpoint.
Balanced forces do not cause movement or a change in speed.
Unbalanced forces cause an object to move in the direction of the greater force.

Examples of balanced forces acting on an object

Pool balls that are balanced being struck by an unbalanced force.
Lifting weights The downward pull of gravity is balanced by the resistance force of the weight stand.
Using a car jack creates an unbalanced force upward.
A car at rest being struck by another car causes the forces to be unbalanced and movement in the direction of the force.

A simple test to see if a number is prime or composite. All you do is find the square root of the number. Next, find all the prime numbers of this number. If none of these prime numbers are a factor of the number then the number is prime.

How do thunderstorms form? In this video, I will cover the basics of these exciting storms.Here is how a thunderstorm forms
Step 1 Warm moist air is heated and begins to rise upward.
Step 2 As this warm air rises it begins to cool, condenses and begins to form clouds
Step 3 This warm air will continue to rise and will encounter cold air which will cool the moisture in the clouds and ice may form
Step 4 Eventually the cooled moisture and ice will begin to fall to the earth This action creates a downdraft
5. The updrafts continue feeding warm humid air and the falling moisture create downdrafts. This creates convection currents. You can see what convection currents look like. The warm water is in red and the cool water is blue.
These convection currents create the most violent stage of the thunderstorm
Lightning and strong winds are produced
6. Eventually the downdrafts will stop the updrafts of warm air
7 When the warm moist air is cut off the storm begins to dye off

There are three main types of thunderstorms; orographic, air mass, and frontal.
