Irvin Ramirez Concept Map:06
Major functions of the nervous system:
Receiving and perceiving special sensations (taste, smell, vision, sounds)
Integration of sensory information from different parts of the body and processing them.
Reception of general sensory information (touch, pressure, temperature, pain, vibration)
Response generation.
Major divisions and subdivisions of the nervous system:
The central nervous system is made up of the brain and spinal cord.
The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
Classification of neurons:
sensory neurons
interneurons
motor neurons
Tissues:
Neuronglia:provide homeostatic support, protection, and defense to the nervous tissue
Nearon:the dendrites, the cell body, and one axon
Connective Tissue Coverings:
perimysium
epimysium
endomysium
Major parts and functions of the brain:
Cerebellum
Occipital Lobe
Midbrain
medulla
Frontal Lobe
Pons
Partietal Lobe
spinal Cord
Major parts and functions of the spinal cord:
Sensory Functions – monitors sensation of touch, pressure, temperature and pain
Autonomic Functions – regulates digestion, urination, body temperature, heart rate
Motor Functions - directs your body's voluntary muscle movements
Action potential & the Nerve Impulse:
rapid sequence of changes in the voltage across a membrane
sends the nerve impulse is called the presynaptic cell , and the cell that receives the nerve impulse is called the postsynaptic cell
Cranial nerves;
Accessory nerve
Facial nerve
Optic Nerve
Terminal Nerve
Spinal nerves:
mixed nerves that interact directly with the spinal cord to modulate motor and sensory information from the body's periphery
Neurotransmitters:
endogenous chemicals that allow neurons to communicate with each other throughout the body
Compare & contrast the autonomic nervous system:
The autonomic nervous system controls the internal organs and glands of the body, whereas the somatic nervous system controls the voluntary muscles of the body
Reflex arc:
Receptors
Motor Neuron
Effectors
Sensor Organ
Spinal Cord
Disorders/Diseases:
Spinal muscular atrophy
Epilepsy
Brain Tumors
Drugs of Abuse:
marijuana and heroin, can activate neurons because their chemical structure mimics that of a natural neurotransmitter in the body
