Term

Neuralgila cells

 

 

Definition
provise scaffolding for neurons
Term
Graded potenital
Definition
short lived depolarizations or hyperpolarizations of an area of membrane. These changes cause local flows of curren
Term
Action Potential
Definition
a short-lasting event in which the electrical membrane potential of a cell rapidly rises and falls
Term
neural transmitter
Definition
chemical that transmits information across the junction (synapse) that separates one nerve cell (neuron) from another nerve cell or a muscle.
Term
Acetylcholine
Definition
a neurotransmitter in both the peripheral nervous system (PNS) and central nervous system (CNS) in many organisms including humans.
Term
dopamine
Definition
is a catecholamine neurotransmitter present in a wide variety of animals, including both vertebrates and invertebrates. In the brain, this substituted phenethylamine functions as a neurotransmitter, activating the five known types of dopamine receptors—D1, D2, D3, D4, and D5—and their variants.
Term
serotonin
Definition
It is a well-known contributor to feelings of well-being; it is also known to contribute to happiness.
Term
Right Lobe
Definition
Spacial, time, art/music, motor to left hand, recognize faces
Term
Left lobe
Definition
verbal, calculating, analytical, interpretation of speech,motor to right hand
Term
Pre central gyrus
Definition
the primary motor area of the cerebral cortex.
Term
Post central gyrus
Definition
the primary sensory area of the cerebral cortex
Term
Pons
Definition
This white matter includes tracts that conduct signals from the cerebrum down to the cerebellum and medulla, and tracts that carry the sensory signals up into the thalamus.[2]
Term
Medulla
Definition
it synthesizes, stores, and releases catecholamines.
Term
Spinal cord
Definition
The brain and spinal cord together make up the central nervous system
Term
Broca's area
Definition
Speech Production
Term
Wernicke's area
Definition
involved in the understanding of written and spoken language
Term
Limbic
Definition
Sense danger.
Term
Lateralization of brain function
Definition
specialization of the brain, with some skills, as language, occurring primarily in the left hemisphere and others, as the perception of visual and spatial relationships, occurring primarily in the right hemisphere.
Term
Thalamus
Definition
relaying sensation, spatial sense, and motor signals to the cerebral cortex
Term
Hypothalamus
Definition
functioning to regulate bodily temperature, certain metabolic processes, and other autonomic activities.
Term
Pineal gland
Definition
secretes the hormone melatonin
Term
Colliculus
Definition
concerned with visual and auditory reflexes.
Term
Choroid plexus
Definition
produce spinal fluid
Term
amygdala
(almond shaped)
Definition
primary role in the processing and memory of emotional reactions,
Term
Meninges
Definition
Protect CNS
Term
sagittal sinus
Definition
crucial large vein that goes over the top of the skull from front to back and then splits to take blood from the brain back toward the heart.
Term
Arachnoid mater
Definition
designed to create a protective barrier to the brain.
Term
cerebral Spinal Fluid
Definition
It mainly cushions the brain to make knocks to the head have less of an effect. It also helps nourish, support and remove metabolic wastes.
Term
Blood Brain barrier
Definition
protect the brain from changes in the levels in the blood of ions, amino acids, peptides, and other substances.
