Question 2

Match the lobes, labelled a. through d., to their descriptions. (Options may be used more than once or not at all.)
-contain the region responsible for personality traits

Accepted Answer

The frontal lobes of the brain are responsible for various functions, including personality, decision-making, and problem-solving.

Answer: B 
 The temporal lobes contain areas responsible for memory, language, and emotion. Personality traits are also influenced by the temporal lobes.

Answer: C or A 
 Parietal lobes are primarily involved in processing sensory information, such as touch and spatial awareness.

-located in front of the central sulcus

Accepted Answer

The frontal lobes are located in front of the central sulcus, which separates them from the parietal lobes located behind it.

Question 8

Match the lobes, labelled a. through d., to their descriptions. (Options may be used more than once or not at all.)
-initially process somesthetic sensation and proprioception

Accepted Answer

The parietal lobes initially process somesthetic sensation (touch, temperature, and pain) and proprioception (awareness of one's own body position and movements).

Answer: D 
 The frontal lobes are responsible for higher-level thinking and decision-making, as well as controlling voluntary movements.

Question 9

Match the system, labelled a. through c., with the characteristics. (Options may be used more than once or not at all.)
-chemical messengers travel long distances

Accepted Answer

Chemical messengers traveling long distances are primarily the function of the endocrine system, which uses hormones to affect target cells throughout the body. The nervous system primarily communicates through electrical and chemical signals across synapses, which are generally short-range. While both systems can influence the same target cells, the endocrine system is better suited for broader signaling.

Question 10

Match the system, labelled a. through c., with the characteristics. (Options may be used more than once or not at all.)
-chemical messengers released only in response to an action potential

Accepted Answer

Chemical messengers released only in response to an action potential are a characteristic of the nervous system, but not specifically the endocrine system.

Question 11

Match the lobes, labelled a. through d., to their descriptions. (Options may be used more than once or not at all.)

Accepted Answer

The occipital lobes are responsible for initially processing visual input.

Answer: B 
 The temporal lobes are not responsible for initially processing visual input, but instead are involved in processing auditory information and recognizing faces.

Answer: C 
 The parietal lobes are involved in processing sensory information from the body and the environment, but are not primarily responsible for processing visual input.

Answer: D 
 The frontal lobes are involved in higher level cognitive processes such as decision making, planning, and problem solving, but are not primarily responsible for processing visual input.

Question 12

Match these brain structures, labelled a. through e., with their associated descriptions. (Options may be used more than once or not at all.)
-is concerned with the coordination of motor activity initiated by higher brain centres; compares the "intentions" of the higher centres with the "performance" of the muscles, and corrects any "errors"

Accepted Answer

The cerebellum is specifically concerned with coordination of motor activity and comparing intentions with performance to correct errors.

Answer: C
 The brain stem is involved in basic life-sustaining functions such as breathing and heart rate, and is located between the spinal cord and higher brain centres.

Answer: D
 The basal nuclei are involved in the control of voluntary motor movements and are located deep within the brain.

Answer: E
 The cerebral cortex is responsible for many higher brain functions such as perception, consciousness, and thought.

Answer: B
 The hypothalamus is involved in a wide range of functions including autonomic regulation, hormone release, and control of hunger and thirst. It does not specifically relate to motor activity coordination.

Question 13

Match the system, labelled a. through c., with the characteristics. (Options may be used more than once or not at all.)
-alters target cells by release of chemical messengers that interact with specific receptors of the target cells

Accepted Answer

Both the nervous and endocrine systems alter target cells through the release of chemical messengers. The nervous system uses neurotransmitters, while the endocrine system uses hormones, both of which interact with specific receptors on their target cells.

Question 14

Match these brain structures, labelled a. through e., with their associated descriptions. (Options may be used more than once or not at all.)
-accomplishes final sensory perception

Accepted Answer

The cerebral cortex is responsible for final sensory perception.

Answer: A
 The cerebellum is not associated with final sensory perception, but it is involved in coordinating movement, balance, and posture.

Answer: C
 The brain stem controls vital functions such as breathing and heart rate, and plays a role in relaying sensory and motor information.

Answer: D
 The basal nuclei (also called basal ganglia) are involved in motor control and learning.

Answer: B
 The hypothalamus is involved in regulating a variety of physiological functions, including hunger, thirst, body temperature, and circadian rhythms, among others.
