Neuro anatomy pt 1 Flashcards
(48 cards)
What is the function of the central nervous system
To integrate and control center
What is the function of Peripheral nervous system
Communicate with CNS and the rest of the body.
What is the function of the sensory division
Conducts impulses receptors to the CNS
What is the function of the Automatic nervous system
Conducts impulses from CNS to cardiac,muscles and glans
What is the Sympathetic division
Mobilizing the body during activity
What is the parasympathetic division
To conserve energy and promote house-keeping functions at rest.
What is the Diencephalon composed on
Thalamus,Hypothalamus and epithalamus
What is the brain stem composed of
midbrain,pons,medulla
What is gray matter composed of
Non-myelinated neurons,neuron cell bodies
What is white matter composed of
Myelinated axons and some that are not
What do ventricles of the brain contain
They contain CSF and ependymal cells
What does the cerebral cortex allow
To perceive, communicate,remember,understand ,appreciate and voluntary movement.
What are the 3 functional areas of the cerebral cortex
Motor,sensory, association
What is contralateral
When each hemisphere does what the opposite side function.
Also, it is motor innervation
What is lateralization
Specialization of the cortical function
What are pyramidal cells
They are large neurons that allow control of skeletal muscles.
What happens when you have a stroke
Voluntary movements were lost, but reflex contraction is still possible.
What is the function of primary motor cortex
The role of the primary motor cortex is to generate neural impulses that control the execution of movement.
What is the function of the Premotor cortex (3)
Plan movements by selecting and sequencing basic motor movements into complex tasks, coordinate movements and can control voluntary actions that DEPEND on sensory feed back
What is the Broca area
Specialized in speech and preparation of speaking.
What is the frontal eye field
Controls voluntary movements
What is the primary somatosensory cortex
Receives info from somatic sensory receptors and proprioceptors.
What does the somatosensory association cortex do
integrate and analyze somatic imput, meaning you don’t need to look to know what it is.
What does the primary visual cortex do
map of the visual space of the retina , receives and integrates .
