Where is the somatosensory cortex located
|
Parietal lobe
|
Where is the motor cortex located
|
Frontal lobe
|
First order neurons is responsible for?
|
Transmit sensory information from the periphery to the CNS
|
Second order neurons is responsible for?
|
Communiciate with various reflex networks and sensory parthways in the spinal cord and travel directly to the thalamus
|
Third order neuronds is responsible for?
|
Relaying information from the thalamus to the cerebral cortex
|
The somatosensory System is organized
|
It is organized segmentally into dermatomes, with each segment supplied bya s single dorsal root ganglion that contains the neuronal cell bodies for the sensory units of the segment
|
Dermatones
|
The region of the body wall that is supplied by a single pair of dorsal root ganglia.
|
Reticular formation
|
It helps matian consciousness, causes awakening from sleep and contributers to regulating muscle tone.
controlls basic breathing, eating and locomotion functions. alarm and arousal system. |
Cerebrum
|
It is the largest part of the brain
it is made up of the right and left hemisphere. Each hemisphere controls the contralateral side of the body. Each hemisphere has four lobes |
Major divisions of the brain
|
The forebrain- cerebrum and the diencephalon
midbrain Hind brain : pons medulla oblongata cerebellum |
There are four lobes
|
Frontal lobe, parietal lobe, occipital lobe, temporal lobe
|
Frontal lobe
|
Contains the motor cortex
|
Parietal lobe
|
Somatosensory cortex
|
Temporal lobe
|
Auditory and olfactory stimuli
|
Occipital Lobe
|
Interprets visual stimuli
