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
