Each oligodendrocyte forms one segment of myelin for several adjacent axons.Oligodendrocytes are found only in the central nervous system, which comprises the brain and spinal cord.

In humans, the medulla region of the brain is mainly responsible for the regulation process of respiration. It is also called the respiratory rhythm centre. The chemosensitive area located near the respiratory centre sends signals across nerve impulses to alter the rate of expiration to eliminate compounds.
Answer:
The correct answer will be option- C.
Explanation:
Lipase is the enzymes which aid in the digestion of the fats in the body. The main types of digestive lipases are secreted by the pancreas which acts on the glycerol of the triglycerides. The pancreatic lipase acts on the fats in the small intestine which break down the fats into smaller molecules called micelles.
Other type of lipases are present in the body which also helps in the digestion of the fats like lipoprotein lipase which acts on the lipoproteins formed by the breakdown of the cholesterol-like low and very low density lipoproteins. These lipoproteins in the blood are activated by the Apoc-II component and after the breakdown of lipoproteins delivers them to peripheral tissues.
Thus, Option-C is the correct answer.

Answer:
A-Band
Explanation:
Sarcomere is the basic unit of skeletal muscle and shows various striations under the microscope.
Anisotropic band or A-Band is the portion of sarcomere that contains both the thick and thin filaments . A-Band appaers dark under the microscope. Thick filaments are consist of actin and thin filaments consists of myosin.
I-Band contains only thin filaments of myosin. H- zone contains only thick filaments and no thin filament. Sarcomere is the unit of a skeletal muscle. Synapse is the junction between two neurons.
Thus, the correct answer is option (A).
