A) pallidotomy.
B) papilledema.
C) paresis.
D) paresthesia.

Accepted Answer

Swelling of the optic disk is known as papilledema. A is incorrect, as pallidotomy is a surgical procedure for Parkinson's disease. C is incorrect, as paresis describes weakness or partial paralysis. D is incorrect, as paresthesia describes abnormal sensations such as tingling or numbness.

A) chorea.
B) cerebral palsy.
C) cerebrospinal.
D) cephalalgia.

Accepted Answer

Cephalalgia is the medical term for a headache.

Question 6

Nerve cells that transmit impulses to the CNS are called:
A) sensory.
B) motor.
C) receptors.
D) autonomic.

Accepted Answer

Sensory neurons are responsible for transmitting impulses from sensory receptors (such as in the skin or eyes) to the central nervous system (CNS).

Question 7

An artificially induced trance is known as:
A) hypnosis.
B) coma.
C) stroke.
D) somnambulism.

Accepted Answer

An artificially induced trance is known as hypnosis.

Question 8

The surgical incision into the skull is:
A) craniectomy.
B) craniotomy.
C) encephalotomy.
D) cranioplasty.

Accepted Answer

A craniotomy is the surgical incision into the skull to gain access to the brain for various procedures such as removing a tumor, clot or managing bleeding. A craniectomy involves removal of a portion of the skull and is typically done in emergency situations. Encephalotomy refers to an incision into the brain tissue itself, and cranioplasty refers to the repair or reconstruction of the skull after damage or surgery.

Question 9

The medulla oblongata regulates and controls all of the following except:
A) breathing.
B) swallowing.
C) vomiting.
D) temperature.

Accepted Answer

The medulla oblongata controls many vital functions such as breathing, swallowing, and vomiting, but it does not regulate temperature. The hypothalamus is responsible for regulating body temperature.

Question 10

Difficulty in comprehending written language is called:
A) dysphasia.
B) akinesia.
C) dementia.
D) dyslexia.

Accepted Answer

Difficulty in comprehending written language is a characteristic of dyslexia. Dysphasia refers to difficulty in producing or understanding spoken language. Akinesia refers to a loss of voluntary movement. Dementia is a general term for decline in cognitive function.

Question 11

All of the following statements are true of the nervous system except:
A) The two divisions are the central nervous system (CNS) and the peripheral nervous system (PNS).
B) The CNS includes the brain and spinal cord. It is enclosed by the bones of the skull and spinal column.
C) The nervous system has two principal tissue types: neurons and neuroplagia.
D) The PNS consists of the network of nerves and neural tissues branching throughout the body from 12 pairs of cranial nerves and 31 pairs of spinal nerves.

Accepted Answer

The nervous system has two principal tissue types: neurons and neuroplagia. This statement is not correct as the correct term is neuroglia or glial cells, not neuroplagia.

Question 12

Which lobe contains centers for auditory and language input?
A) parietal
B) frontal
C) temporal
D) occipital

Accepted Answer

The temporal lobe contains centers for auditory and language input, such as the primary auditory cortex and Wernicke's area. The parietal lobe is involved in sensory processing and spatial awareness, the frontal lobe is involved in executive functions and decision making, and the occipital lobe is responsible for visual processing.

Question 13

Inflammation of the brain is known as:
A) cephalalgia.
B) concussion.
C) ataxia.
D) encephalitis.

Accepted Answer

Inflammation of the brain is specifically known as encephalitis.

Question 14

An outer sheath that envelops a nerve fiber is a:
A) neuron.
B) neuroblast.
C) neurilemma.
D) neurocyte.

Accepted Answer

The outer sheath that envelopes a nerve fiber is called the neurilemma. A neuron is a nerve cell, a neuroblast is an immature nervous system cell, and a neurocyte is a term not commonly used to describe nerve cells.

Question 15

Temporary loss of consciousness caused by a head injury is called:
A) coma.
B) concussion.
C) chorea.
D) syncope.

Accepted Answer

Temporary loss of consciousness caused by a head injury is called a concussion. A coma is a state of prolonged unconsciousness, chorea is a movement disorder, and syncope is a brief loss of consciousness due to reduced blood flow to the brain.

Question 16

Which of the following is NOT a function of the hypothalamus?
A) acts as a regulator
B) directs bone growth
C) produces neurosecretions
D) produces hormones

Accepted Answer

The hypothalamus is responsible for regulating various bodily functions, including body temperature, hunger, thirst, fatigue, and sleep. It produces hormones and neurosecretions that affect other parts of the body. However, it does not direct bone growth, which is primarily controlled by hormones produced by the pituitary gland and other endocrine organs.

Question 17

The brain's major motor area is located in the ________ lobe.
A) parietal
B) frontal
C) temporal
D) occipital

Accepted Answer

The motor cortex, which is the brain's major motor area, is located in the frontal lobe.

Question 18

Paralysis that affects one side of the body is called:
A) apraxia.
B) paraplegia.
C) hemiplegia.
D) quadriplegia.

Accepted Answer

Hemiplegia is the medical term for paralysis that affects one side of the body. Apraxia refers to a motor disorder involving difficulty with purposeful movements, paraplegia refers to paralysis of the lower half of the body, and quadriplegia refers to paralysis of all four limbs.
