A & P III Nervous System

2.

Name the two parts of the Central Nervous System (CNS)

Explanation
The Central Nervous System (CNS) consists of two main parts: the brain and the spinal cord. The brain is responsible for processing information, controlling body functions, and coordinating actions. It is located in the skull and is protected by the skull bones. The spinal cord is a long, thin bundle of nerves that extends from the brain down through the spinal column. It acts as a communication pathway between the brain and the rest of the body, transmitting signals to and from the brain. Together, the brain and spinal cord form the central control center of the nervous system.

Name the two main divisions of the nervous system

Somatic Nervous System
Central Nervous System
Autonomic Nervous System
Peripheral Nervous System

Correct Answer(s)

A. Central Nervous System
A. Peripheral Nervous System

Explanation

The two main divisions of the nervous system are the central nervous system and the peripheral nervous system. The central nervous system consists of the brain and spinal cord, which are responsible for processing and coordinating information. The peripheral nervous system includes all the nerves outside of the central nervous system, which transmit information between the central nervous system and the rest of the body.

The nerve cells that convey information from receptors in the body to the CNS. Also called sensory neurons.

Efferent
Neurons
Neuroglia
Afferent

Correct Answer

A. Afferent

Explanation

Afferent neurons, also known as sensory neurons, are responsible for transmitting information from receptors in the body to the central nervous system (CNS). These neurons play a crucial role in the sensory process, allowing us to perceive and interpret various stimuli from our environment. Unlike efferent neurons, which transmit signals from the CNS to the rest of the body, afferent neurons are specifically involved in relaying sensory information to the brain and spinal cord for processing and response. Neuroglia, on the other hand, are non-neuronal cells that provide support and protection to neurons in the nervous system.

Conveys information from CNS to muscles and glands. Also called sensory neurons.

Efferent
Neurons
Neuroglia
Afferent

Correct Answer

A. Efferent

Explanation

Efferent neurons are responsible for conveying information from the central nervous system (CNS) to muscles and glands. They transmit signals that control muscle movement and activate glands to release hormones or other substances. These neurons are also known as motor neurons. Afferent neurons, on the other hand, transmit sensory information from the body to the CNS. Neuroglia refers to the supportive cells in the nervous system that provide structure and support for neurons.

This system has efferent neurons that conduct impulses from CNS to skeletal muscles or voluntary muscles.

Peripheral
Autonomic
Somatic
Central

Correct Answer

A. Somatic

Explanation

The correct answer is somatic because the question is asking for the system that has efferent neurons that conduct impulses from the central nervous system (CNS) to skeletal muscles or voluntary muscles. The somatic nervous system is responsible for voluntary movement and controls the skeletal muscles, allowing us to consciously control our body movements.

This system is made up of efferent neurons that convey impulses from CNS to smooth muscle tissue, cariac muscles and glands.

Peripheral
Autonomic
Somatic
Central

Correct Answer

A. Autonomic

Explanation

The correct answer is Autonomic. The autonomic nervous system is responsible for regulating involuntary bodily functions. It is made up of efferent neurons that transmit signals from the central nervous system to smooth muscle tissue, cardiac muscles, and glands. This system controls processes such as heart rate, digestion, and glandular secretion.
