Question 1

Your cat always walks up to you and wants you to pet it on its ________ surface,but your dog lies on its back and presents its _________ surface for you to scratch.​ 
A)ventral; dorsal 
B)dorsal; ventral 
C)rostral; caudal 
D)caudal; rostral

Accepted Answer

The cat presents its ventral surface for petting, and the dog presents its dorsal surface for scratching. Therefore, the correct choices are ventral for a cat and dorsal for a dog. Choices A, C, and D are also anatomical terms, but they do not correctly describe the situation with the cat and dog in the question.

Question 2

The anterior cingulate cortex (ACC)is located _________ the posterior cingulate cortex (PCC).​ 
A)behind 
B)in front of 
C)below 
D)above

Accepted Answer

The term "anterior" means "in front of" and the term "posterior" means "at or near the hind end". Therefore, the ACC is located in front of the PCC.

Question 3

Researchers investigating appetite distinguish between the roles played by the ventromedial hypothalamus and the lateral hypothalamus.Where are these two structures located relative to one another?​ 
A)The lateral hypothalamus is contralateral to the ventromedial hypothalamus. 
B)The lateral hypothalamus is rostral to the ventromedial hypothalamus. 
C)The lateral hypothalamus is closer to the midline than the ventromedial hypothalamus. 
D)The ventromedial hypothalamus is located closer to the midline than the lateral hypothalamus.

Accepted Answer

The ventromedial hypothalamus is located closer to the midline than the lateral hypothalamus.

Question 4

Given the fact that the motor cortex controls movement of contralateral body parts,if your grandfather experiences damage to his right hemisphere motor cortex due to a stroke,it is likely that he will​ 
A)not be able to walk at all because he will be paralyzed from the waist down. 
B)have some paralysis in the left side of his body. 
C)not be able to understand anything you say to him. 
D)have some paralysis on the right side of his body.

Accepted Answer

Since the motor cortex controls movement of contralateral (opposite) body parts, damage to the right hemisphere motor cortex will result in some paralysis on the left side of the body. Option A is incorrect because the question doesn't mention the stroke affecting the spinal cord, so we cannot assume there will be paralysis from the waist down. Option C is incorrect because it is not related to the motor cortex. Option D is incorrect because the question specifically mentions damage to the right hemisphere, which would result in paralysis on the left side of the body.

Question 5

Cerebrospinal fluid (CSF)is secreted by the​ 
A)meninges. 
B)subarachnoid space. 
C)choroid plexus. 
D)ventricles.

Accepted Answer

Cerebrospinal fluid is secreted by the choroid plexus, which is a network of small blood vessels in the ventricles of the brain. The other options mentioned (meninges, subarachnoid space, and ventricles) are all involved in the circulation and/or containment of CSF, but do not directly secrete it.

Question 6

A subdural hematoma is a "bruise" that often occurs following a head injury and affects a layer of the membranes that cover the central nervous system and the peripheral nerves.Given your knowledge of anatomical terms,which of the following is the likely location of this type of injury?​ 
A)the scalp 
B)the meninges 
C)the lateral ventricles 
D)the central canal of the spinal cord

Accepted Answer

A subdural hematoma affects the layer of membranes that cover the central nervous system and the peripheral nerves, which are the meninges. The scalp is not a layer of membrane covering the central nervous system, the lateral ventricles are filled with cerebrospinal fluid and not covered by membranes, and the central canal of the spinal cord is located within the spinal cord itself and not surrounded by the meninges.

Question 7

In order to assess the size of the lateral ventricles in patients with schizophrenia,Dr.Weinberger has decided to use a coronal or frontal section.In other words,he is looking at a plane of section that is​ 
A)perpendicular to the ground, dividing the brain from front to back. 
B)perpendicular to the ground, dividing the brain from side to side. 
C)parallel to the midline, dividing the brain from side to side. 
D)parallel to the ground, dividing the brain from top to bottom.

Accepted Answer

The answer of In order to assess the size of...

Question 8

Anatomical sections that divide the brain parallel to the midline are known as _________ sections.​ 
A)sagittal 
B)coronal 
C)horizontal 
D)axial

Accepted Answer

Sagittal sections divide the brain parallel to the midline, while coronal and horizontal sections divide the brain perpendicular to the midline. Axial sections are also known as transverse sections and divide the brain horizontally. Therefore, the only correct answer is A) Sagittal.

Question 9

Researchers who wished to have a full view of a structure from the top of the head would use a _________ section.​ 
A)sagittal 
B)coronal 
C)horizontal 
D)midsagittal

Accepted Answer

A horizontal section would provide a view of the structure from the top of the head. Sagittal sections would provide a side view, coronal sections would provide a front/back view, and midsagittal sections would provide a view directly down the center of the head.

Question 10

Most of the neural input to your left eyebrow originates in the motor cortex of the left hemisphere.In other words,your eyebrow receives input from the _________ hemisphere.​ 
A)proximal 
B)distal

A)central and peripheral nervous systems. 
B)peripheral nervous system only. 
C)lateral and distal ventricles of the brain. 
D)ventricles, subarachnoid space, and central canal of the spinal cord.

Accepted Answer

The answer of Cerebrospinal fluid (CSF)may be found in the​ 
A)central...

Question 12

The subarachnoid space is found between the arachnoid layer and the​ 
A)pia mater. 
B)dura mater. 
C)skull bones. 
D)lateral ventricles.

Accepted Answer

The subarachnoid space is located between the arachnoid layer and the pia mater, which is the innermost layer of the meninges that directly covers the brain and spinal cord. It is filled with cerebrospinal fluid (CSF) that helps cushion and protect the brain and spinal cord from physical trauma. It also provides a route for the exchange of nutrients, waste products, and other substances between the blood vessels and nervous tissue.

Question 13

The superior and inferior colliculi are located in the midbrain.Where are these two structures located relative to one another?​ 
A)The superior colliculi are located above the inferior colliculi. 
B)The superior colliculi are located below the inferior colliculi. 
C)The superior colliculi are closer to the midline than the inferior colliculi. 
D)The superior colliculi are farther away from the midline than the inferior colliculi.

Accepted Answer

The superior colliculi are located above the inferior colliculi in the midbrain.

Question 14

You just heard about a friend who has a tumor on the meninges of her right temporal lobe.This means that the tumor is ________ to the midline of the brain.​ 
A)contralateral 
B)medial 
C)ventral 
D)lateral

Accepted Answer

The right temporal lobe is on the lateral side of the brain, which means that the tumor is also on the lateral side.

Question 15

Early computerized tomography (CT)equipment could take images from only one perspective,the axial or horizontal section.This means that the resulting images were from sections that are _________ to the ground,dividing the brain from _________.​ 
A)perpendicular; front to back 
B)perpendicular dividing the brain from side to side. 
C)parallel to the midline, dividing the brain from side to side. 
D)parallel to the ground, dividing the brain from top to bottom.

Accepted Answer

Early CT equipment produced images parallel to the ground, which means the images were horizontal sections dividing the brain from top to bottom.

Question 16

Which layer(s)of the meninges is/are missing in the peripheral nervous system?​ 
A)pia mater, arachnoid layer, and dura mater 
B)pia mater only 
C)pia mater and dura mater only 
D)arachnoid layer and subarachnoid space

Accepted Answer

The peripheral nervous system lacks the arachnoid layer and the subarachnoid space, which are present in the central nervous system's meninges.

Question 17

Which of the meninges is described as a leatherlike tissue that follows the contours of the skull bones?​ 
A)pia mater 
B)dura mater 
C)arachnoid layer 
D)subarachnoid space

Accepted Answer

The dura mater is a tough, leatherlike tissue that adheres to and follows the contours of the skull bones. The pia mater is a delicate, highly vascularized layer that adheres to the surface of the brain, while the arachnoid layer is a thin, delicate membrane that lies between the dura mater and the pia mater. The subarachnoid space is a space filled with cerebrospinal fluid located between the arachnoid layer and the pia mater.

Question 18

Which layers of the meninges are found in the peripheral nervous system?​ 
A)pia mater, arachnoid layer, and dura mater 
B)pia mater only
