Answer:
Homeostasis
Explanation:
Homeostasis is the maintenance of a steady-state/condition in the body to ensure the optimal workings of the cells. Blood sugar level is one of the variables in the body that also has to be maintained through positive and negative feedback loops to maintain the desired level. Insulin is the hormone used for negative feedback (to reduce the blood sugar level when it goes higher than the normal level) and Glucagon is the hormone for positive feedback (to raise the blood sugar level when it goes below the normal levels).
The Serratus anterior in man is homologous to the Serratus ventralis muscle in the cat. The Serratus anterior is a muscle that originates on the surface of the 1st to 8th ribs at the side of the chest and insects along the entire anterior length of the medial border of the scapula. The Serratus anterior acts to pull the scapula forward around the thorax. Serratus ventralis in the cats looks like fingers because it attaches to the ribs, but has nothing to attach to between the ribs.
