○ plantar
○ abdominal
○ crossed extensor
question 4
1 pts
which neuroglial cell would you expect to help prevent leakage in the blood - brain barrier and provide structural support?
○ schwann
○ ependymal
○ astrocyte
○ oligodendrocyte

Explanation:

First Question (Reflex related)

The withdrawal reflex is the reflex that occurs in response to pain, causing the body part to pull back. The plantar reflex is related to the sole of the foot, abdominal reflex to the abdomen, and crossed extensor is a different reflex. So the correct option is the one with withdrawal.

Astrocytes are neuroglial cells that help maintain the blood - brain barrier and provide structural support. Schwann cells are involved in myelination of peripheral nerves, ependymal cells line the ventricles, and oligodendrocytes myelinate central nervous system axons.

Answer:

A. withdrawal (assuming the first option is labeled A, etc. If options are as given: withdrawal)
