Explanation:

Question 79

Cholinergic terminals are defined as axon terminals that secrete acetylcholine. So the statement is correct.

The lateral corticospinal tract originates in the brain (cortex) and terminates in the spinal cord, and is located on the lateral side of the spinal cord. The ventral spinothalamic and lateral spinothalamic tracts carry sensory information (originate in spinal cord, terminate in thalamus). The dorsal corticospinal tract is not a standard tract; the main corticospinal tract with brain - to - spinal cord origin and lateral location is the lateral corticospinal tract.

• The choroid is a vascular layer, not transparent with aligned collagen fibers.
• The ciliary body is involved in accommodation, not having the described structure.
• The sclera is tough and white, not transparent.
• The cornea is a transparent structure of the eye with regularly aligned collagen fibers.
• The lens is transparent but its structure is different (composed of lens fibers, not collagen fibers in the same aligned manner as cornea).

Answer:

True
