Answer:
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.

Answer:
Lack of ADH increase urine volume and decrease urine concentration.
Explanation:
ADH is a hormone which is responsible for regulation of urine volume. The hormone is released in the blood from the posterior pituitary when the ion concentration in the blood becomes high.
This hormone acts on the nephron especially on distal convoluted tubule and collecting duct and increases their permeability towards water which in absent of ADH is impermeable to water.
This increased permeability allows the reabsorption of water from these sections which reduces the blood volume and helps in producing concentrated urine.
