Overview The Nervous System. The nervous system of the human is the most highly organized system of the body. The overall function of the nervous system.
And Brain Organization
  Consists of the brain stem  pathway for all nerves entering and leaving the brain  The Pons-- involved with sleep and alertness; connects brain.
NERVOUS SYSTEM Coordinates all activities in the body by transmitting messages back and forth to every cell of the body through nerves.

ASSESSING THE SENSORY- NEUROLOGICAL SYSTEM

Structures 4 Cerebrum  Cortex 4 Frontal lobe  Temporal lobe 4 Parietal lobeOccipital lobe 4 Thalamus  Hypothalamus 4 Cerebellum  Brainstem 4 Midbrain  Medulla 4 Meninges  Ventricles

Functions What are the functions of… Cerebrum: Largest part of brain Cortex: Outer layer of cerebrum; controls most conscious processes Frontal Lobe: Emotional expression, Broca’s area (expressive language) (Continued)

Functions What are the functions of… Temporal lobe: Hearing, taste, smell, memory, Wernike’s (language comprehension) (Continued)

Functions What are the functions of… Parietal: Sensory input Occipital lobe: Vision and spatial relationships (Continued)

Functions What are the functions of… Thalamus: Clusters multiple sensory stimuli Hypothalamus: Controls autonomic nervous system and pituitary gland Cerebellum: Coordination, equilibrium (Continued)

Functions What are the functions of… Brainstem: Involuntary survival behaviors; includes midbrain, medulla and pons Midbrain: Visual, auditory, pupils, and eye movements (Continued)

Functions What are the functions of… Medulla: Regulates heart, respiratory rates, B/P, and protective reflexes Pons: Helps with respiratory function, facial sensation and movement (Continued)

Functions What are the functions of… Meninges: 3 layers (pia, arachnoid, dura); protect brain and spinal cord Ventricles: 4 cavities; capillaries produce and reabsorb CSF (Continued)
