– The neurosensory system serves as the body’s communication network.
– It processes information from the outside world (through the sensory portion) and coordinates and organizes the functions of all other body systems.
– Major parts of the neurosensory system include the brain, the spinal cord.
Central Nervous System (CNS)
– It includes the brain and spinal cord. These fragile structures are protected by the skull and vertebra, cerebrospinal fluid (CSF), and three membranes: the dura mater, the pia mater and the arachnoid membrane.
– The cerebrum, the largest part of the brain, houses the nerve center that controls motor and sensory functions and intelligence.
– The cerebrum divided into hemispheres.
– Several fissures divide the cerebrum into four lobes:
– Frontal lobe: the site of personality; memory, reasoning, concentration, and motor control of speech.
– Parietal lobe: the site of sensation, integration of sensory information, and spatial relationships.
– Temporal lobe: the site of hearing, speech, memory, and emotion.
– Occipital lobe: the site of vision and involuntary eye movement
