Determine whether each statement refers to the central nervous system or the peripheral nervous system. consists of the brain and spinal cord

consists of the nerves outside the brain and spinal cord

collects information from sensory organs

processes information from sensory organs


Answer and Explanation:

Consists of the brain and spinal cord

- central nervous system

Consists of the nerves outside the brain and spinal cord

-peripheral nervous system

Collects information from sensory organs

-peripheral nervous system

Processes information from sensory organs-central nervous system.

The CNS is made up of the brain and the spinal cord. The PNS consists of nerves, which link the CNS to various receptors and effectors.


The central nervous system

  • consists of the brain and spinal cord-
  • processes information from sensory organ

The peripheral nervous system

  • collects information from sensory organs
  • consists of the nerves outside the brain and spinal cord

Further Explanation:

The nervous system is subdivided into; the central nervous system (CNS), which includes the brain and spinal cord, within the vertebral column; and the peripheral nervous system, which includes nerves that branch into the rest of the body from the brain and spinal cord. Nervous tissue responds to electrical impulses, allowing for communication between different regions of the body.

The peripheral nervous system is further divided into the somatic nervous system responsible for carrying out sensory and motor information between the peripheral nervous system- including sensory organs like the eyes; and central nervous system; and the autonomic nervous system which regulates involuntary bodily functions like heartbeat, breathing and blood flow. The ANS is mainly acts unconsciously and affects smooth muscle and internal organs. It is related to homeostasis- where the body maintains a constant internal balance in pH, temperature, blood pressure etc.

Somatosensory pathways contain primary, secondary, and tertiary neurons which are capable of processing information about vibration, touch, temperature, and pain- information is passed on after receiving stimuli from the body's internal or skin receptors. Thus the precision is greater in the lips and fingers (directly involved in tactile interactions with stimuli) than on the back.
