4 Nervous cells Flashcards
What are the tree-like projections emerging from the cell body of a neuron?
Dendrites
What component of a neuron receives input?
The Dendrites
An axon carries information towards or away from the soma (Cell body)?
Away
What is the most common type of neuron morphology found in the body?
Multipolar
The myelin sheaths surrounding axons in the peripheral nervous system are known as:
Schwann cells
Oligodendrocytes are found in the peripheral or central nervous system?
Central
The gaps between adjacent myelin sheaths along an axon are known as:
Nodes of Ranvier
Ependymal cells are neuroglia which perform what function?
Secrete Cerebrospinal fluid
Macrophage cells of the nervous system are known as:
Microglia
Satellite Glial Cells are found covering what structures?
Neural cell bodies (soma)
What cells line the ventricles of the brain and the central canal of the spinal cord?
Ependymal Cells
Circulation of cerebrospinal fluid is achieved by what structures?
Cillia and Microvilli of the Ependymal Cells
What type of cells are responsible for metabolic regulation in the extracellular space of the nervous system?
Astrocytes
Which cells interact with capillaries in order to form the blood-brain barrier?
Astrocytes
Cleaning of debris and removal of dead cells in the nervous system is carried out by what type of cell?
Microglia
Grey matter consists of myelinated or unmyelinated nervous tissue?
Unmyelinated
White matter consists of myelinated or unmyelinated nervous tissue?
Myelinated
The peripheral nervous tissue of the spinal chord is white or grey matter?
White
The limbic area of the brain responsible for recall of memories is found in which lobe of the cerebral cortex?
Parietal lobe
The relay centre between the cerebral cortex and the incoming sensory input is known as:
The Thalamus
Fluid balance, body temperature and sleep/wake regulation are controlled by what structure of the brain?
The Hypothalamus
In what area of the brain is the conscious mind considered to be located?
The Cerebral Cortex
The primary somatic cortex is located in which lobe of the cerebral brain?
Frontal Lobe
What type of neuron is abundant in the gyri of the cerebral hemispheres and is important for motor function?
Pyramidal Neurons
Coordination of movement instructions is carried out buy which brain structure?
The Cerebellum
The gyri particular to the cerebellum are known as:
Folio
Cells with extensive networks of dendrites found in the cerebellum are known as:
Purkinje Cells
An inhibitory neurotransmitter released by purkinje cells in the cerebellum which aid in coordination of movement is known as:
GABA
The parietal layer of the Cerebellar folio is known as:
The Molecular Layer
The layer beneath the molecular layer and purkinje cell bodies within the folio of the cerebellum is known as:
The Granular Layer
The tuft like structure consisting of capillaries ensheathed by ependymal cells is known as:
The Choroid Plexus
Non communicating Hydrocephalus indicates an obstruction within the ventricles or at the arachnoid villi?
Within the Ventricles
