Ch. 12 And 13 Flashcards
Four divisions of the brain
Cerebrum
Diencephalon
Cerebellum
Brainstem
Spinal cord
Nervous tissue that forms an extension of the inferior brainstem
Grey matter
Nuclei
White matter
Myelinated axons
Neural tube
That which begins to develop into the CNS by 4th week of fetal development
5 lobes of the cerebral hemispheres
Frontal lobes Parietal lobes Occipital lobes Temporal lobes Insula
Cerebral cortex
Cerebrum’s outer layer of grey matter
Neocortex
Majority of cerebral cortex is this
Three types of neocortex
Primary motor cortex
Primary sensory cortices
Association areas
Neocortex
Functions in conscious processing
Ei. Planning of movement and incoming sensory information
Association areas
Unimodal- integrate only one type of information
Multimodal- integrate several types of information
Basal nuclei
Group of nuclei in the cerebrum that function in movement
Three types of basal nuclei
Caudate nuclei
Putamen
Globus pallidus
Tracts
White matter that carries info to the nuclei
Nuclei
Bundles of cell bodies that send outgoing info along the nuclei
Three types of white matter
Commissural fibers- connect right and left hemispheres
Projection fibers- connect outer cerebrum w other parts of CNS
Association fibers- connect gyri
Limbic system
Functions in memory, learning, emotion and behavior
Diencephalon
Central core of the brain
Four divisions of the diencephalon
Subthalamus
Thalamus
Hypothalamus
Epithalamus
Cerebellum
Coordination of movement
Brainstem
Controls homeostatic functions
Mid brain
Superior portion of brainstem
Functions in movement, sensation, and reflexes
