I can name the bones of the and what type of joint the Ankle Joint is

I can name the bones of the and what type of joint the Knee Joint is

I can name the major bones of the and what type of joint the Hip Joint is

I can name the bones of the and what type of joint the Wrist Joint is

I can name the bones of the and what type of joint the Elbow Joint is

I can name the bones of the and what type of joint the Shoulder Joint is

Let’s introduce you to the ANATOMICAL POSITION.

In humans, the standard anatomical position is with the body standing up straight and facing forward, with arms by the sides of the body and palms facing forward. The legs are straight, and the feet are slightly apart from one another and turned outward slightly.

This is used as a starting point for describing the movements the body performs

Here’s a couple of short video that should help you get started on the next task:

Joint Movements (Part A)

Joint Movements (Part B)

We need to be able to identify the movements performed at each joint as well as the muscles that cause these movements to occur. But first, you are going to do a bit of research. Below is a table for you to complete and your tasks are as follows:

Provide a description of what the movement looks like.
In which joints of the body can we find this movement performed?
Provide an image

Anatomy of a Skeletal Muscle

We have three different types of muscle in the body:

Skeletal

This type of muscle attaches from one bone to another and by contracting and relaxing, it allows the body to move.

Cardiac

This muscle type is only found in the heart and is responsible for the heart beating by contracting and relaxing. It’s sole purpose is to pump blood from the heart to the lungs and the rest of the body.

Smooth

This type of muscle is found in a number of organs of the body and you cannot control their contractions. Moving food along from your stomach to your intestines is an example as well as pushing blood along your arteries.

Rules Around Muscle Function

1. Muscles can only PULL (Contract). They always pull on the bone they insert onto (where the muscle ends) and PULL towards the ORIGIN of the muscle (where the muscle “begins”). With Biceps, the muscle pulls on the Radius to “bend the elbow” (in the diagram on the previous page).

2.When the muscle contracts, the length of the muscle gets SHORTER.

3. Muscles always WORK IN PAIRS. (This is important so pay attention!) When one muscle CONTRACTS (and shortens in length) , it’s “opposite muscle” RELAXES. The Biceps is located on the front of the upper arm. It’s opposite muscle is the TRICEPS BRACHII but let’s just call it Triceps and it’s located on the back of the upper arm.

This process of muscles working in pairs where one muscle contracts and shortens while its opposite muscle relaxes and lengthens is called RECIPROCAL INHIBITION. This process works for every skeletal muscle in the body.

Two Terms You Need To Know:

When we look at the muscle pairs working when a joint is moving, one of the muscles has to be the one pulling / contracting. We call this muscle the AGONIST.The opposite muscle of the pair that is relaxing, we call the ANTAGONIST.

CHECKLIST:

I can explain the Principle of Reciprocal Inhibition
I can describe the difference between an Agonist and Antagonist muscle

Identifying the Muscle and Movements They Enable

Major Muscles of the Human Body

Your task is to (on the doc to the side of this info, you are to do this individually):

Identify the correct “ANATOMICAL NAME” for each of the muscles given below (column 2).

Describe the LOCATION of the muscle (column 3). Lets keep it fairly general in our description.

Identify the MOVEMENT(s) PERFORMED AT EACH JOINT. You need to be aware that some muscles perform more than one movement and sometimes across two joints.\

The 1st example is already been done for you!

ASSESSMENT PART 1

Demonstrating your understanding* Choose a skill from:

A Front Kick
A Clean & Jerk
A Deadlift

You must learn how to demonstrate and explain your chosen skill. Your explanation/demonstration must:
