---|---|---|---|---|
What is an Oligodendrocyte.
This type of glia cell provides a myelin sheath around axons within the brain and spinal cord.
|
What are the nodes of Ranvier.
The narrow gaps between Schwann cells.
|
What is the pons.
This part of the Brainstem separates the midbrain and medulla oblongata.
|
What is the Diencephalon.
This part of the CNS is comprised of the thalamus and hypothalamus.
|
What are gyri.
These are elevated surface ridges on the cerebrum.
|
What is a microglial cell.
This type of glial cell aids in immune defense. It phagocytes bacterial cells and other debris.
|
What is a multipolar neuron.
This type of neuron has one axon with multiple dendrites.
|
What is the cerebellum.
A large mass of tissue located below the occipital lobes of the cerebrum and posterior to the pons and medulla oblongata.
|
What is the Spinal Cord.
This part of the CNS is a slender nerve column which passes downward from the brain into the vertebral canal.
|
What is the occipital lobe.
This lobe of the brain is located in the very back (posterior region). The visual association area / primary visual cortex is located here.
|
What is an ependymal cell.
These glial cells form a membrane around specialized brain parts.
|
What is an interneuron.
This type of neuron lies completely within the brain and spinal cord. It conducts impulses to other neurons within the brain and spinal cord.
|
What is the midbrain.
This short section of the Brainstem is located between the diencephalon and the pons.
|
What is the number 31.
The spinal cord consists of this number of segments.
|
What is the central sulcus.
This structure divides the parietal lobe from the frontal lobe.
|
What is an astrocyte.
This type of glial cell is commonly found between neurons and blood vessels.
|
What is a motor neuron.
This type of neuron conducts impulses out of the brain or spinal cord.
|
What is the reticular formation.
Scattered throughout the medusa oblongata, pons, and midbrain, this formation is a complex network of nerve fibers associated with tiny islands of gray matter.
|
What is the thalamus.
This part of the diencephalon acts as a central rely station for sensory impulses ascending from other parts of the nervous system to the cerebral cortex.
|
What are sulci.
These are shallow gloves on the cerebrum.
|
What is a Schwann cell.
These neuroglia are located in the peripheral nervous system and produce a myelin sheath around axons of myelinated neurons.
|
What is an axon.
This part of the neuron conducts impulses away from the neuron cell body.
|
What is the cerebellum.
This portion of the CNS functions to coordinate complex skeletal muscle movements and helps maintain posture.
|
What is the hypothalamus.
This region of the diencephalon maintains homeostasis.
|
What is the cerebrum.
This region of the brain controls higher brain functions including sensory perception and storing memories.
