In the cerebral cortex. A deep fold tha involves the entire thickness of the
brain wall. ---------CORRECT ANSWER-----------------Fissure
Also called Prosencephalon. Is the rostral-most (forward-most) portion of
the brain. One of three primary portions of the brain during early
development of the CNS. It controls body temperature, reproductive
functions, eating, sleeping, and any display of emotions. ---------CORRECT
ANSWER-----------------Forebrain
Functions in Frontal lobe ---------CORRECT ANSWER-----------------
Thought, decision, feeling, moving. Located at the front of each cerebral
hemisphere.
A nerve cell cluster or a group of nerve cell bodies located in the peripheral
nervous system (PNS). ---------CORRECT ANSWER-----------------Ganglia
Gated ion channels ---------CORRECT ANSWER-----------------Actual
passageways (pores) for ions across the membrane; active channels can
be opened or closed by electrical, chemical or physical stimuli.
Do provide structural support-a scaffoloding around which the brain is built.
---------CORRECT ANSWER-----------------Glia (astrocytes)
,Golgi apparatus ---------CORRECT ANSWER-----------------Modifying,
sorting and packing macromolecules (proteins, lipids) in the soma.
A major part of the CNS, consisting of nerve cell bodies, dendrites and
axons. ---------CORRECT ANSWER-----------------Grey Matter
Gustatory Cortex ---------CORRECT ANSWER-----------------Brain structure
responsible for the perception of taste.
A ridge on the cerebral cortex. Generally surrounded by one or more sulci.
---------CORRECT ANSWER-----------------Gyrus
Hindbrain ---------CORRECT ANSWER-----------------Also called
Rhombencephalon. A developmental categorization of the CNS in
vertebrates.
Medical condition in which there is an abnormal accumulation of
cerebrospinal fluid in the ventricles of the brain. ---------CORRECT
ANSWER-----------------Hydrocephalus
Hyperpolarization ---------CORRECT ANSWER-----------------When voltage-
gated Na? Channels close and voltage-gated K+ open. K+ ions leave the
cell and causes the inside of the cell to become more negative than the
outside. When the inside of the neuron becomes even more negative than
at the resting state (as it happens after the firing of an action potential) - the
neuron is said to be hyperpolarized - it is difficult or impossible to generate
,new active electrical currents (as it is difficult to raise the voltage of the
neuronal membrane above the threshold)
Also called Pituitary Gland. Is an endocrine gland about the size of a pea. It
is a protrusion off the bottom of the hypothalamus. ---------CORRECT
ANSWER-----------------Hypophysis
Hypothalamus ---------CORRECT ANSWER-----------------A thumb sized
region deep in the middle of the brain that monitors the body's internal
functions and helps regulate things like hunger, thirst, body temperature,
and hormones.
A complex set of direct influences and feedback interactions among
hypothalamus, pituitary gland, and the adrenal glands. Release of cortisol,
the 'stress hormone'. ---------CORRECT ANSWER-----------------
Hypothalamic-Pituitary-Adrenal Axis (HPA axis)
When a neuron is att rest (not firing electrical signals), there is a differential
concentration of ions outsode and inside the neuron. ---------CORRECT
ANSWER-----------------Resting membrane potential
Neurotransmitter which effects muscle activation in PNS, and arousal;
sustained attention; learning & memory, in CNS ---------CORRECT
ANSWER-----------------Acetylcholine.
Toward nose. ---------CORRECT ANSWER-----------------Rostral (anterior)
, Rough endoplasmatic reticulum (RER) ---------CORRECT ANSWER----------
-------In the soma. Covered with ribosomes; the site of protein synthesis.
nerve impulse conduction along myelinated fibers where an action potential
"jumps" from one node to the next ---------CORRECT ANSWER----------------
-Saltatory conduction (Latin saltare "jump")
Santiago Ramón Y Cajal (1880s) ---------CORRECT ANSWER-----------------
"The father of modern neuroscience"
Glial cell in PNS. Have a significant role in controlling the microenvironment
of the sympathetic ganglia. ---------CORRECT ANSWER-----------------
Satellite cells
Schwann cells ---------CORRECT ANSWER-----------------Myelin sheath
around axons in PNS.
Carry impulses from peripheral body parts into the brain or spinal cord. -----
----CORRECT ANSWER-----------------Sensory (afferent) neurons
Septum Pellucidum ---------CORRECT ANSWER-----------------A thin,
triangular, vertical membrane separating the anterior horns of the left and
right lateral ventricles of the brain. It runs as a sheet from the corpus
collosum and down the fornix.
