Astrocytes
(Appearance and function) correct answers - big and star shaped
- communicated with neurons and blood vessels
- maintains neural integrity
Microglia
(appearance and function) correct answers - smaller glial cell
- perform phagocytosis to engulf pathogens
Ependymal cells
(appearance and function) correct answers - simple cuboidal cells
- lines the cavities of brain and spinal cord
- helps produce cerebrospinal fluid
oligodendrocytes correct answers - myelinate axons in the CNS
- one cell can myelinate many axons
Schwann cells correct answers - myelinate axons in the PNS
- can only myelinate part of one axon
The cerebrum correct answers - telencephalon
- diencephalon
Telencephalon correct answers - interprets sensory signals
- sends motor signals
- decision making
longitudinal fissure correct answers separates cerebral hemispheres
Lateral Sulcus correct answers Divides the temporal from frontal and parietal lobes.
precentral sulcus correct answers - anterior border of the motor cortex
central sulcus correct answers - divides frontal and parietal lobes
