Nervous System Flashcards
The ________ is very important in helping to maintain the homeostasis (balance) of the human body.
nervous system
A series of sensory receptors work with the nervous system to provide information about changes in both the internal and external environments.
Nervous System
A complex of interconnected systems in which larger systems are comprised of smaller subsystems each of which have specific structures with specific functions.
Nervous System
It is made up of the brain and spinal cord
CNS (central nervous system)
The CNS is composed of two major interconnected organs:
- brain
- spinal cord
The _________ is responsible for higher neural functions such as memory, learning, and emotion.
CNS (central nervous system)
Made up of all the nerves that lead into and out of the CNS
Peripheral Nervous System (PNS)
Made up of all the nerves that lead into and out of the CNS
Peripheral Nervous System (PNS)
Peripheral Nervous System (PNS)
For sensing: Sends this information to the CNS through sensory neurons
Sensory (Afferent)
Peripheral Nervous System (PNS)
Takes the information to send to a target cell through efferent neurons
Motor (Efferent)
_______ - can be divided further into two categories
- Somatic NS
- Autonomic NS
Motor Division
_______ - can be divided further into two categories
- Somatic NS
- Autonomic NS
Motor Division
It Controls Voluntary movement Targets: Skeletal Muscle
Somatic NS
Controls involuntary movement Targets the sympathetic and parasympathetic NS
Autonomic NS
Autonomic Nervous System (ANS) has a 2 major divisions
- Sympathetic Division
- Parasympathetic Division
