The Nervous System Includes:
|
The brain, the spinal cord, complex sense organs and the nerves that interconnect
|
|
2 Major Anatomical Divisions of the Nervous System:
|
Central Nervous System (CNS)
Peripheral Nervous System (PNS)
|
|
CNS consists of:
|
The spinal cord & brain
|
|
CNS is responsible for:
|
Integrating, processing, & coordinating sensory data and motor commands
|
|
Motor Commands do what?
|
Control or adjust the activities of the peripheral organs such as skeletal muscles
|
|
PNS consists of:
|
All the neural tissue outside the CNS
|
|
PNS is responsible for:
|
Delivery of sensory information to the CNS, carries motor commands to peripheral tissue
|
|
What carries out sensory information and motor commands in the PNS?
|
Bundles of axons or nerve fibers (called pheripheral nerves)
|
|
Nerves connected to the brain are called?
|
Cranial Nerves
|
|
Nerves attached to the spinal cord are called?
|
Spinal Nerves
|
|
The PNS is divided into 3 different divisions:
|
Afferent Division, Efferent Division, and Effectors .... (Sympathetic Division & Parasympathetic Division)
|
|
Afferent Division of the PNS does what?
|
Brings sensory information to the CNS from receptors in perpheral tissues and organs
