Summative Test on Nervous System

The nervous system is responsible for regulating various functions in the human body. It is divided into the Central Nervous System (CNS) and Peripheral Nervous System (PNS). Which of the following is a major component of the CNS?

• Autonomic nerves

• Cranial nerves

• Somatic nerves

• Spinal cord

The brainstem is one of the critical parts of the brain responsible for several automatic functions. Which function is regulated by the brainstem?

• Breathing and heart rate

• Emotional responses

• Memory storage

• Visual processing

The cerebrum is the largest part of the brain and is divided into several lobes. Which lobe is responsible for visual processing?

• Frontal lobe

• Occipital lobe

• Parietal lobe

• Temporal lobe

The spinal cord serves as a channel between the brain and the body. It is divided into segments. How many segments make up the spinal cord?

• 15

• 20

• 31

• 40

Which part of the nervous system is referred to as the "emotional brain"?

• Brainstem

• Cerebellum

• Limbic system

• Frontal lobe

The nervous system has two major divisions: the CNS and the PNS. If the CNS is considered the processing center, what is the primary role of the PNS?

• To regulate emotions and memory

• To process voluntary movements only

• To connect the CNS to organs and limbs

• To control autonomic functions like breathing

A patient has difficulty controlling voluntary movements of their muscles after a nerve injury. Which part of the nervous system is most likely affected?

• Autonomic nervous system

• Limbic system

• Parasympathetic division

• Somatic nervous system

Imagine a situation where a person experiences rapid breathing, increased heart rate, and sweating while preparing for an important exam. Which division of the nervous system is responsible for these reactions?

• Central

• Parasympathetic

• Sympathetic

• Somatic

The brain controls various functions through its different lobes. Which lobe is primarily responsible for reasoning, planning, and problem-solving?

• Frontal lobe

• Occipital lobe

• Parietal lobe

• Temporal lobe

A person is unable to maintain their balance and coordination after a head injury. Which part of the brain is likely damaged?

• Brainstem

• Cerebellum

• Cerebrum

• Limbic system
