Vocabulary 2 Flashcards
A branched extension of a nerve cell which impulses from other cells at synapses are transmitted to the cell body
Dendrite
Processes and transmits information through electrical and chemical signals.
Neuron
Is a nerve fiber that transmit information to different neurons, muscles and glands.
Axon
Usually around the axon of a neuron. Essential for the proper functioning of the nervous system.
Myelin
Is usually the recovery phase after orgasm during which it is physiologically impossible for man to have additional orgasms.
Refractory period
Is a structure that permits neuron to pass and electrical or chemical signal to another cell.
Synapse
The absorption by a presynaptic never ending of a neurotransmitter that it has secreted.
Reuptake
Are endogenous opioid inhibitory neuropeptides. They are produced by the central nervous system and pituitary gland.
Endorphins
Is a chemical that binds to a receptor and activates the receptor to produce a biological response.

Paul Broca
Best known for his contributions to evolutionary theory. He established that all species of life have descended over time from common ancestors.
Charles Darwin
He Is one of the leading researchers in cognitive neurosciences, the study of the neural basis of mind.
Michael Gazzaniga
Was a neuropsychologist who together with David hunter and Torsten Nils won the 1981 Nobel Price in Physiology and Medicine for his works with split-brain research.
Roger Sperry
He is best known for his descriptions of the aphasias, disorders interfering with the ability to communicate is speech or writing.
Carl Wernicke
Is a class of signaling molecules produced by glands in multicellular organisms that are transported by the circulatory system to target distant organs to regulate physiology and behavior
Hormones
Combines a series of X-ray views taken from many different angles and computer processing to create cross- sectional images of the bones and soft tissues inside your body
CT Scan
Detects abnormalities in the brain or electrical activity of the brain.
Electroencephalogram
Is a imaging test that uses a radioactive substance called a tracer to look for disease in the body.
PET Scan
Is a medical imaging technique used in radiology or investigate the anatomy any physiology of the body in both health and disease.
