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.
Cortex involved in somatic sensation. ---------CORRECT ANSWER------------
-----Somatic Sensory Cortex
Serves a conduit for signals between the brain and the rest of the body.
Controls simple muscular reflexes without input from the brain. ---------
CORRECT ANSWER-----------------Spinal Cord
Norepinephrine (noradrenaline) ---------CORRECT ANSWER-----------------
Neurotransmitter in PNS with fight or flight responce, and in CNS with
alertness/arousal effect. Related to anxiety disorders, panic attacks,
narcolepsy, ADHD, PTSD and depression.
,Superior ---------CORRECT ANSWER-----------------Above.
One of two main divisions of the autonomic nervous system (ACS). The
ACS functions is to regulate the body's unconscious actions. The
sympathetic nervous system SNSs primary process is to stimulate the
body's fight-or-flight response. ---------CORRECT ANSWER-----------------
Sympathetic Nervous System
Symptoms of MS ---------CORRECT ANSWER-----------------Visual, motor,
sensory, coordination, balance. Bowel, bladder, sexual, cognitive.
Neurotransmitter that effect motor function; reward/motivation;
cognition/emotion; attention, and are related to Parkinson's disease, drug
abuse/addiction, schizophrenia, bipolar disorder and ADHD. ---------
CORRECT ANSWER-----------------Dopamine
Tegmentum ---------CORRECT ANSWER-----------------A part of the
midbrain extending from the substantia nigra to the cerebral aqueduct in a
horizontal section of the midbrain. It forms the floor of the midbrain that
surrounds the cerebral aqueduct.
Lobe responsible for hearing, speaking, learning. Located beneath the
lateral fissure on both hemispheres. ---------CORRECT ANSWER--------------
---Tenporal lobe
Tetrodoxin ---------CORRECT ANSWER-----------------acts by blocking action
potentials through inhibiting sodium (Na⁺) channels (without any changes to
, potassium, K⁺, channels). Thus, it prevents neurons from signaling and
causes the paralysis of the diaphragm due to the nerve and muscle block.
Rounded structure in the middle region of the brain that relays sensory
signals to the cerebral cortex. Only a very small part of the thalamus is in
any way related to the limbic structure set. ---------CORRECT ANSWER-----
------------Thalamus
Transmembrane pumps ---------CORRECT ANSWER-----------------Actively
transport (pump) ions across the membrane.
A method of performing prefrontal lobotomy in which the surgical knife was
inserted above the eyeball and moved to cut brain fibers. ---------CORRECT
ANSWER-----------------Transorbital Lobotomy
Trepanation ---------CORRECT ANSWER-----------------The process of
making a burr hole in the skull in order to improve the brain pulsations and
hence the overall well being.
Glutamate. ---------CORRECT ANSWER-----------------Most common
Excitatory neurotransmitter.
Ventral (inferior) ---------CORRECT ANSWER-----------------Toward belly.
Here is where the cerebrospinal fluid (CSF) is produced. There are four
ventricles in the brain, and the two largest are the lateral ventricles in the
