Answer:

It has an anterior and posterior face. The greater tubercle serves as attachment site for three of the rotator cuff muscles – supraspinatus, infraspinatus and teres minor – they attach to superior, middle and inferior facets respectively. The lesser tubercle is much smaller, and more medially located on the bone

Answer:

c. Beginning with the return from the systemic circulation, blood enters the right atrium. 

a. Blood enters the right ventricle from the right atrium through the right atrioventricular valve which is also known as the tricuspid valve

d. The right ventricle contracts next, which forces blood up through the right semilunar valve which is otherwise known as the pulmonary valve .

e. After circulating through the pulmonary capillaries, the blood returns to the left atrium. 

f. From the left atrium, blood moves through the left atrioventricular valve which is also referred to as the bicuspid or mitral valve.

b. From the left ventricle, the blood is pumped up to aorta the through the left semilunar valve which is sometimes referred to as the aortic valve.

Interphase-intermediate phase, DNA replicates

Prophase -coils into chromosomes, chromosomes are made of two chromatids, which join at the centromere at this stage.

Metaphase -Chromosomes line up in the middle of cell on spindles

Anaphase - Chromosomes are pulled apart to opposite ends of the cell by the spindles

Telophase - The cell splits into two cells, and the chromosomes uncoil and begin from the interphase stage again

During the _______ phase, the muscle is returning to resting length.

tangare [24]

Answer:

The correct answer is: Eccentric phase.

When talking about movement, we are talking about the activation of muscle fibers in order for this process to happen. In order for this to happen, motor neurons must activate the phases of muscle excitation, contraction and relaxation, so that the sarcomeres, and thus the fibers, can generate movement.

In essence, there are three stages, or phases, to complete muscle movement: the concentric phase, which is when the muscle fibers are excited and begin the process of contraction. This means the muscle fibers will contract and generate movement, generating a shortening. Then we have the isometric stage, a moment in which there is no longer any more shortening of the muscle fibers, so basically, the movement is held and there is no further contraction, but neither is there relaxation of the muscle fibers. Finally, we have the eccentric phase. This phase is characterized precisely because it is the moment when the muscles begin to return to their resting position.
