A single motor neuron together with all the skeletal muscle fibers it innervates is called a motor unit.
- Motor neurons are more than just relays for the motor commands sent down the hierarchy from higher levels. They themselves are parts of intricate circuits that carry out extensive information processing.
- Due to their highly branching, intricate dendritic trees, motor neurons are able to integrate inputs from several other neurons and generate accurate outputs.
- A single motor neuron, and nothing else, innervates each and every muscle fiber (make sure you understand the difference between a muscle and a muscle fiber). However, several muscle fibers can be innervated by a single motor neuron.
- A motor unit is the aggregate of a single motor neuron and all of the muscle fibers that it innervates. The innervation ratio refers to how many fibers a motor unit innervates.

3 is enzymes, 7 is c, 6 is either c or d, 5 is B, 4 is c
Renin is an enzyme that helps control blood pressure and regulate levels of sodium and potassium in the body. Angiotensinogen is the hormone that causes the narrowing of blood vessels. It is released from liver to form angiotensin.
<h3>What is the role of angiotensin?</h3>
Angiotensinogen is a hormone that on hydrolysis forms angiotensin
Angiotensinogen is hydrolyzed by renin enzyme and forms angiotensin.
This angiotensin helps to increase blood pressure by the process of vasoconstriction, increased aldosterone biosynthesis and renal actions.
Thus, it can be concluded renin hydrolyzes angiotensinogen, which is released from the liver, to form angiotensin.
