Answer:
The correct answer is e. all of the above.
Explanation:
Nurse cells are also called sertoli cells and are located in the seminiferous tubules in the testes. They provide nourishment to the growing sperms by providing nutrients from surrounding cells.
During the development of of sperms they become genetically different from other cells so nurse cells form blood testes barrier to protect them from immune cells.
Nurse cells concentrate the testosterone in seminiferous tubules which is necessary for proper development of sperms. They also secrete inhibin which stop FSH secretion from anterior pituitary therefore regulate the spermatogenesis.

The answer to the question: What thoracic muscle is the prime mover of shoulder flexion, would be, A: Pectoralis minor.
Explanation:
The movement, and stability of the shoulder joint, and the arm itself, depends mostly on many muscles and tendons that keep it from coming apart with movement. While all of them work together to protect this joint and permit arm movement, some of them will aid in a certain type of movement, while others will antagonize these first. The important thing here is that as your joint moves, these muscles activate to ensure stability and movement. During flexion, which is literally the movement of bringing the arm closer to the body, there are several muscles that act as synergists, meaning, they act together to ensure correct movement and stability. One such muscle is the pectoralis minor, which arises from the ribs, and then inserts into the coracoid process of the scapula. In conjunction with other muscles, the pectoralis minor will be prime in shoulder flexion, and will be aided by others.
