Psych study guide 2 Flashcards
Parasympathetic
nervous system is one of three divisions of the autonomic nervous system. Sometimes called the rest and digest system, the parasympathetic system conserves energy as it slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles in the gastrointestinal tract.
Neurochemicals
is a small organic molecule or peptide that participates in neural activity. The science of neurochemistry studies the functions of neurochemicals.
Testicles
releases testosterone, male sex hormone
Soma
1 of the 5 main parts of a neuron, contains all the DNA, and contains the things that keep the neuron alive.
Reuptake
It is when neurotransmitters are bound to the receptors and then sent back to the original axon.
Ovaries
releases estrogen, female sex hormone
Dendrites
receives electrochemical messages that are sent through the axon.
Potassium(K)
is a mineral and an electrolyte. It helps your muscles work, including the muscles that control your heartbeat and breathing.
MRI
is a medical imaging technique that uses a magnetic field and computer-generated radio waves to create detailed images of the organs and tissues in your body. (track blood flow and brain activity)
Axon
electrochemical messages are sent through the axon.
Sodium(Na)
is a chemical element with the symbol Na (from Latin “natrium”) and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is 23Na.
Pet Scan
shows brain consumption of chemical fuels.
Neurons
is the basic working unit of the brain, a specialized cell designed to transmit information to other nerve cells, muscle, or gland cells. Neurons are cells within the nervous system that transmit information to other nerve cells, muscle, or gland cells. Most neurons have a cell body, an axon, and dendrites.
Sodium-potassium pump
re-separate the (Na) and (K) ions
Thyroid
located in the neck, it controls hormones that boost or reduce metabolism
