It links the brain and the parts of the body below the neck. Purposes of the spinal cord - Correct Answer ️️ -1. to receive sensory information from the PNS to send to the brain for processing. 2. to pass motor information (about movement) from the brain to the PNS so that appropriate actions can be taken. Sensory - Correct Answer ️️ -afferent (incoming information) Motor - Correct Answer ️️ -efferent (outgoing information) Peripheral Nervous System (PNS) - Correct Answer ️️ -Carries information from the sensory organs and internal organs to the CNS and conveys information from the CNS to the muscles, organs and glands. 2 main divions of PNS - Correct Answer ️️ -somatic and autonomic nervous system The somatic nervous system (SNS) - Correct Answer ️️ -a network of sensory nerves that carry sensory information to the CNS and motor information from the CNS The Autonomic nervous system - Correct Answer ️️ -connects the CNS to the body's internal organs (such as the heart, stomach and liver) and glands (such as sweat, salivary and adrenal glands) provides feedback to the brain about their activities. Homeostasis - Correct Answer ️️ -a state of steady internal conditions Sensory neurons - Correct Answer ️️ -Carry 'incoming information' about a sense in the PNS (an injury for example) to the CNS. motor neurons - Correct Answer ️️ -Carry 'outgoing information' from the CNS to muscles that control movement in the PNS. interneurons - Correct Answer ️️ -link sensory and motor neurons. Found only in the CNS. 3 divisions of the Autonomic NS - Correct Answer ️️ -parasympathetic, sympathetic and enteric nervous system.
