Question 1

Vertebrae

Answer 1

Cervical 7 Thoracic 12 Lumbar 5 Sacrum 5 fused Coccyx 4 fused

Question 2

Joint Movement

Answer 2

Flexion.

Something that results in the folding or closing down of body parts thus creating a body that takes up less space. When the knee flexes, the ankle moves closer to the buttock, and the angle between the femur and tibia gets smaller.

Extension. Parts of the body becoming longer, expanding, and maximising the area that they take up in space.

Abduction and Adduction:

Abduction is a movement away from the midline – just as abducting someone is to take them away. For example, abduction of the shoulder raises the arms out to the sides of the body.

Rotation: This movement occurs about the long axis of a bone and is generally subdivided into medial/inward or lateral/outward rotation.

Medial/inward, you’re point your toes in pigeon toed, and the knees rotate inwards

lateral/outward, you’re pointing your toes out like charlie chaplin, and knees rotate outwards

Question 3

psoas

Answer 3

Deepest muscle of your core, from the 12 thoratic vertebrae, to your 5th lumbar, through your pelvis, then to your femur. Your psoas muscles allow you to bend your hips and legs towards your chest, for example when you are going up stairs. They also help to move your leg forward when you walk or run. Your psoas muscles are the muscles that flex your trunk forward when bend over to pick up something from the floor. They also stabilize your trunk and spine during movement and sitting.

yeah it’s a huge muscle … comes up the inside of one leg, does a big cross over your lower back, and goes up the opposite side of your back!

The eight joints that it crosses over are:
T12 – L1, L1 – L2, L2 – L3, L3 – L4, L4 – L5, L5 – sacrum, sacroiliac joint, and lastly the hip joint.
