For tomorrow's quiz

• gathering information to monitor changes occurring inside and outside the body

  Sensory input
• to process and interpret sensory input and decide if action is needed

  Integration
• A response to integrated stimuli

  The response activates muscle or glands

  Motor Output
• Central Nervous System is made up of the brain, spinal cord and dorsal cavity it located at bottom of occipital L1-L2
• The function of Central Nervous System is to take information and give instruction
• the cns is the command center
• Nerves outside the brain and spinal cord. It is the communication lines
• The peripheral nervous system is divided into two parts the Sensory or afferent and Motor or efferent.
• The Motor or efferent Division is divided into two the Somatic and Autonomic.
• The Autonomic Nervous System is divided into two parts the Sympathetic and Parasympathetic
• Sensory or afferent division carry information to the CNS
• Motor or efferent division carry impulses away from THE CNS
• Sympathetic also known as fight or flight
• parasympathetic division also known as rest and digest
• Sympathetic response to unusual stimulus it takes over to increase activies and remember the E division
• Parasympathetic is housekeeping activities it conserves energy and remember the D division
• Neuron is also called as nerve cell it specialized to transmit messages
• In the neuron anatomy there are two division the dendrites and axon
• Axon conducts impulses away
• dendrites conduct towards the cell body
• Schwann cells form myelin sheath in the PNS
• in the classification of neurons there are two types the sensory neurons and the motor neurons
• sensory neurons carry impulses from the sensory receptors
• motor neurons impulses from the cns to pns
• CNS develops from the ebryonic neural tube four chambers within the brain filled with cereborspinal fluid
• the regions of the brain are cerebral hemisphere, diencephalon, brain stem and cerebellum
• the cerebral hemisphere is also known as cerebrum
• Cerebral hemispheres is the largest and most complex area of the brain
• The cerebral hemisphere has four lobes the frontal lobe, temporal lobe, parietal lobe, and occipital lobe
• The surface of the brain is also called as cerebral cortex
• a distinctive pattern of folds or bumps known as gyri ( gyrus ) and groove known as sulci or sulcus
• these gyri and sulci form important landmarks that allow us to separate the brain into functional centers
• frontal lobe is divided into two parts the primary motor area and broca
• primary motor area sends skeletal muscle
• the broca are involve in our ability to speak
• Temporal lobe is responsible for gustatory, auditory and olfactory
• occipital is responsible for visual
• parietal for sensation
• wernikle area is responsible for interpreting speech
• broca area is responsible for speech production, located in the frontal lobe
