Nervous System Flashcards
What is the CNS made up of?
brain
spinal cord
What is the PNS made up of?
cranial nerves
spinal nerves
Give some examples of cranial nerves
Optic II- vision
Facial VII- sensation in your face and tongue
Olfactory I- smell
What are your spinal nerves responsible for?
sensory afferent
motor efferent
What are lower motor neurons?
neurons with cell bodies in the spinal cord or brain stem which have axons that innervate skeletal muscle
What are upper motor neurons?
neurones that transmit information from the brain to the lower motor neurons and inter motor neurons in the brainstem and spinal cord
What is the cerebellum?
interaction between cerebrum and motor areas of the brain produce smooth, co-ordinated movement and balance
What is the cerebrum?
divided into 2 hemispheres by the longitudinal tissue
outer layer is made up of greta matter
What does the brainstem do?
Sensory and motor pathways
stores importance control centres
nuclei of cranial nerves
control of automatic movement
What does the hypothalamus do?
regulated homeostasis
What does the thalamus do?
sensory input
What does the basal ganglia do?
important in planning, control and coordination of complex movement
What does the frontal lobe do?
speech, personality, memory, movement, planning and execution
What does the premotor area do?
initiation and planning of movement
What does the primary motor area do?
initiates and controls voluntary movement
damage- paralysis
