Organization Of Nervous System Flashcards
(32 cards)
The Nervous system has three major functions:
Sensory functions
Integration functions
Motor functions
Which function monitors internal & external environment through presence of receptors?
Sensory functions
Which function interpretates the
sensory information (information processing)
Integration functions
Which function is a response to information
processed through stimulation of effectors?
Motor functions
There are 3 parts of the brain
Forebrain
Midbrain
Hindbrain
Includes all of the cerebrum and the internal nuclei
Telencephalon
the internal nuclei in telencephalon
Basal ganglia
Hippocampus
Olfactory bulb
Amygdala
Outermost layer of the cerebrum
Cerebral cortex
Composed of 2 - 4mm of gray matter
Cerebral cortex
Up to 6 horizontal layers with unique neuronal projections
Cerebral cortex
Basal ganglia Function
Motor control; connections with motor cortex and thalamus
includes the thalamus and hypothalamus
Diencephalon
Telencephalon + diencephalon =
Forebrain
Main integrating centre for sensory information
Thalamus
Main control centre for the autonomic nervous system
Hypothalamus
Receives input from basal ganglia & cerebellum
Thalamus
Mesencephalon divisions
Tectum
Tegmentum
contain nuclei for visual center
superior colliculi
contain nuclei for auditory center
inferior colliculi
Myelencephalon + metencephalon =
Hindbrain
Contains ascending & descending sensory and motor tracts connecting the cerebrum to the spinal cord
medulla oblongata
myelencephalon contains
Medulla oblongata
Metencephalon contains
Pons & cerebellum
connect information between cerebellum and cerebrum
Pons
