Question 12

​The ____ act like the male sex hormones.
A) ​stimulants
B) ​depressants
C) ​anabolic steroids
D) ​hallucinogens

Accepted Answer

Anabolic steroids are synthetic substances that mimic the effects of the male sex hormones, such as testosterone. They are often used illicitly by athletes and bodybuilders to enhance muscle growth and performance.

Question 13

A bundle of fibers located outside the central nervous system is called a(n) ____.​
A) ​tract
B) ​ganglion
C) ​nerve
D) ​axon

Accepted Answer

A bundle of fibers located outside the central nervous system is called a nerve. Tracts refer to bundles of fibers within the central nervous system, ganglia refer to clusters of nerve cell bodies outside the central nervous system, and axons are single fibers that transmit nerve impulses.

Question 14

Descending tracts of the central nervous system that conduct impulses down the spinal cord are concerned with ____ functions.​
A) ​sensory
B) ​motor
C) ​afferent
D) ​interneuron

Accepted Answer

Descending tracts of the central nervous system are responsible for transmitting motor impulses down the spinal cord, allowing for voluntary muscle movements and other motor functions.

Question 15

​Areas of the nervous system known as ____ consist of nerve cells bodies and dendrites.
A) ​white matter
B) ​ganglia
C) ​tracts
D) ​gray matter

Accepted Answer

Gray matter consists of nerve cell bodies and dendrites, whereas white matter consists of myelinated axons. Ganglia are clusters of nerve cell bodies outside the central nervous system, and tracts are bundles of axons within the central nervous system.

Question 16

​Valium is an example of a(n) ____.
A) ​depressant
B) ​stimulant
C) ​hallucinogen
D) ​anabolic steroid

Accepted Answer

Valium is a type of benzodiazepine which is a class of drugs that act as central nervous system depressants. Therefore, the best choice is A) depressant.

Question 17

​The nerve fibers on the nerve cell that receive signals are called ____________________.

Accepted Answer

The answer of ​The nerve fibers on the nerve cell...

Question 18

​The space that separates the meninges from the vertebrae is called the ____ space.
A) ​subarachnoid
B) ​subdura
C) ​epidural
D) ​submater

Accepted Answer

The space that separates the meninges from the vertebrae is called the epidural space. The subarachnoid space is the space between the arachnoid mater and the pia mater. The subdura space is the potential space between the dura mater and arachnoid mater that can occur with trauma or bleeding. There is no term called submater.

Question 19

​The ____ division of the autonomic nervous system stimulates and speeds up certain bodily activities.
A) ​parasympathetic
B) ​sympathetic
C) ​somatic
D) ​central

Accepted Answer

The sympathetic division of the autonomic nervous system is responsible for stimulating and speeding up certain bodily activities, such as increasing heart rate and dilating the pupils. The parasympathetic division, in contrast, slows down bodily activities and promotes relaxation. The somatic division is responsible for voluntary movements, while the central nervous system includes the brain and spinal cord.

Question 20

​A bundle of fibers inside the central nervous system is called a ____.
