Answer: Glial cells called ASTROCYTES help maintain the blood-brain barrier, whereas SCHWANN CELLS create the myelin that envelopes axons
Explanation: Glial cells are specialized cell that are found in both central and peripheral nervous systems, that surrounds the neurones, providing them with support and insulation. There are different types of Glial cells these includes:
- Astrocytes: they maintain the blood brain barrier.
- Schwann cells: create the myelin that envelopes axons of the peripheral nervous system neurones.
- satellite cells: These cells help regulate the external chemical environment of neurones.
- Microglia: they clean up cellular debris through phagocytosis.
- Oligodendrocytes: create the myelin that envelopes axons of the central nervous system
The extra oxygen is used to restore muscle fibers to their pre-exercise state by doing all of the following except facilitating calcium release from the sarcoplasmic reticulum in the muscle fiber. Thus, the correct option is B.
<h3>What is Respiration?</h3>
Respiration may be defined as the process of acquiring oxygen from outside the body and utilizing it in the process of breakdown of food sources for cellular needs.
The extra oxygen works in the muscle fiber by replenishing the ATP, restocking the myoglobin, and supplying the ATP used to replenish glycogen stores in the muscle fiber.
Therefore, the correct option for this question is B.

Answer:
The glenoid cavity is where the d. humerus articulates with the scapula.
Explanation:
The scapula is the bone that contains the glenoid cavity. The glenoid cavity is a part of the shoulder. This cavity forms the glenohumeral joint along with the humerus. The Humerus is a long bone of the upper arm, and the scapula articulates with this bone to form a ball and socket joint at the shoulder. These are all bones forming the shoulder girdle and upper extremities.
It is the metric unit of measurement for temperature.
