Exam Flashcards
Identifies changes also called stimuli occurring inside and outside the body using sensory receptors
Collection of sensory input (PNS)
Processes analysis in interprets changes then make decisions
Integration
Activating muscles or glands via motor output
Effects a response
Group of neurons within the cns
Nucleuli
Group of neurons outside the cns
Ganglia
Group of nerve fibers axons within the CNS
Track
Group of nerve fibers outside the cns
Nerve
Large mass of nervous tissue located in the cranial activity
Brain
Four major regions of the brain
Cerebrum
Cerebellum
Diacephalon
Brainstem
It is the largest part of the brain also has two hemisphere
Cerebrum
Connected by a thick bundle of nerve fibers called corpus callosum
Cerebral hemisphere
The surface shows ridges of tissues called
Separated by grooves called
Gyri
Sulci
It’s called gray matter or cortex
Outermost layer
Masses of grey matter located deep within the white matter
Basal nuclei or basal ganglia
Has two hemispheres and a convoluted surface
Cerebellum
Provides precise coordination for body movements and help maintain equilibrium
Cerebellum
Gray and white matter
The spinal cord is extended to L2 vertebra but in children it extends to L3 vertebra because their vertebral column is smaller or shorter
Note
How long is spinal cord
42 to 45 cm
Extends from form and magnum to L2 vertebra
Spinal cord
Give rise to 31 pairs of spinal nerves
Note
Group of spinal nerves at the end of the spinal cord is called
Cauda equina
Formed by neutrons and their processes presents in all regions of the body
Peripheral nervous system
Two subdivision in peripheral nervous system
Somatic nervous system
Autonomic nervous system
