The Nervous System Flashcards
It is the body’s major communication and control network in the form of electrical signals, and relayed constantly from the sense organs to and from the brain, through complex networks of neurons on a timescale measured in milliseconds
Nervous system
It consists of the brain and spinal cord. It is the coordinating system for the body.
Schematic
integration center of communication
Thalamus
directs Pituitary gland
Hypothalamus
master gland, metabolism, growth
Pituitary gland
movement
Basal Ganglia
learning, memory
limbic system
higher order processing of information
Cerebrum
hearing, vision
Tectum
heartbeat, circulation and respiration
Medulla
movement production, motivation
Tegmentum
relay station
Pons
movement, balance and coordination
Cerebellum
a long cylinder of nerve tissue that
extends like a tail from the medulla; serves as the pathway
of information
Spinal cord
It consists of peripheral nerves ang ganglia (spinal, cranial, visceral nerves), the between brain and body.
Peripheral nervous system
It controls voluntary movement
Somatic PNS
It controls involuntary movement
Autonomic PNS
controls for ‘fight or flight’ responses
Sympathetic system
controls for ‘rest and digest’ responses
Parasympathetic system
most smallest neurons
granular cells
begins programming a movement for Motor cortex to execute movement
premotor cortex
4 lobes of the cerebral cortex
Frontal lobe
Parietal lobe
Occipital lobe
Temporal lobe
They are the hill/clefts.
Sulci
They are the ridges/valleys formed along the sulci
Gyri
