Nervous System Grade 8 - Review

What is the role of receptors in the nervous system?

• To generate signals
• To receive and detect stimuli from the environment or within the body
• To transmit signals to the central nervous system
• To regulate involuntary bodily functions

Which parts of the body function as recipients of stimuli?

• Brain and spinal cord
• Muscles and bones
• Skin, eyes, ears, nose, and tongue
• Heart and lungs

Which part of the nerve cell receives stimuli?

• Dendrites
• Cell body
• Axon
• Myelin sheath

Which divisions of the nervous system are included in the peripheral nervous system?

• Sympathetic and parasympathetic nervous systems
• Autonomic and somatic nervous systems
• Central and peripheral nervous systems
• Sensory and motor nervous systems

Which division of the peripheral nervous system is responsible for controlling voluntary muscle movements?

• Autonomic nervous system
• Somatic nervous system
• Central nervous system
• Sympathetic nervous system

Which component of the peripheral nervous system is responsible for regulating involuntary bodily functions such as heart rate and digestion?

• Autonomic nervous system
• Somatic nervous system
• Central nervous system
• Sensory nervous system

Which of the following describes the characteristics of the human peripheral nervous system?

• Consists of nerves outside the brain and spinal cord, responsible for transmitting sensory information and controlling motor functions.
• Responsible for processing and integrating sensory information.
• Comprises the brain and spinal cord, coordinating body activities and transmitting signals.
• Plays a role in involuntary bodily functions such as heartbeat and digestion.

What are the roles of the peripheral nervous system?
