Question 1

The SAID principle stands for Specific Adaptations to Imposed ___.

Accepted Answer

Demands

Answer

SAID stands for Specific Adaptations to Imposed Demands, meaning the body adapts specifically to the type and magnitude of stress placed upon it.

Question 2

Which bone forms the rounded posterior portion of the shoulder joint socket?

Accepted Answer

Glenoid fossa of scapula

Answer

The glenoid fossa, a shallow cavity on the lateral scapula, forms the socket of the glenohumeral (shoulder) joint.

Question 3

What is the primary role of the rotator cuff muscles?

Accepted Answer

Stabilizing the humeral head in the glenoid fossa

Answer

The four rotator cuff muscles (SITS) compress and stabilize the humeral head within the shallow glenoid fossa, preventing dislocation during arm movements.

Question 4

During eccentric muscle action, the muscle is:

Accepted Answer

Lengthening while producing force

Answer

Eccentric muscle action occurs when a muscle produces force while being lengthened, such as the biceps during the lowering phase of a bicep curl.

Question 5
