Nervous System
This is the system that controls communication with all other systems in order to maintain homeostasis.
Sensory Input, Integration, Motor Output
What are the three functions of the Nervous System?
Sensory Input
This function of the Nervous System monitors changes inside and outside of the body.
Integration
This function of the Nervous System interprets information to determine what action to take.
Motor Output
This function of the Nervous System responds by sending commands to muscles, organs, and glands.
Central and Peripheral
What are the two major divisions of the Nervous System?
Central
This division of the nervous system is composed of the brain and the spinal cord. It integrates and processes the incoming sensory information and coordinates motor output.
Central
This division of the nervous system is composed of the brain and the spinal cord.
Central
This division of the nervous integrates and processes the incoming sensory information.
Central
This division of the nervous system coordinates motor output
Peripheral
This division of the nervous system is composed of neurons that extend from the central nervous system to spinal or cranial nerves. It relays information to and from the Central Nervous System.
Peripheral
This division of the nervous system is composed of neurons that extend from the central nervous system to spinal or cranial nerves.
Peripheral
This division of the nervous system relays information to and from the Central Nervous System.
Afferent and Efferent
What are the two divisions of the peripheral nervous system?
afferent
Which of the two divisions of the peripheral nervous system is sensory?
efferent
Which of the two divisions of the peripheral nervous system is motor?
Afferent
this division of the peripheral nervous system sends sensory information into the CNS from receptors in the organs: skin, stomach, eyes, etc
Efferent
This division of the peripheral nervous system carries motor commands from the CNS to muscles, organs, and glands: effectors
Effectors
this responds by doing something
Somatic and Autonomic
What are the two divisions of the Efferent division of the peripheral nervous system?
Somatic
this division of efferent division of the peripheral nervous system controls skeletal muscle contractions. This can be conscious (voluntary) or subconscious (involuntary) control.
Autonomic
this division of efferent division of the peripheral nervous system controls smooth muscles, cardiac muscles, and gland secretions. This is subconscious, or involuntary control.
Sympathetic and parasympatheic
What are the two divisions of the autonomic division of the efferent division of the peripheral nervous system?
sympathetic
this division of the autonomic division of the efferent division of the peripheral nervous system increases organ activity during stressful or imaginary situations. It uses large amounts of energy. It is the fight or flight response.
parasymaptheic
this division of the autonomic division of the efferent division of the peripheral nervous system decreases organ activity to calm the body. it restores and conserves energy.
