Intro to neurology
define neurology
study of the nervous system
what surrounds the brain, spinal cord, meninges, cerebrolspinal fluid?
Bones of the skull and spinal column
what is a neuron
impulse conducting cells and are the simple structural units of the nervous system
what kind of messengers are neurotransmitters
chemical messengers
where is the cerebrolspinal fluid produced ?
Choroid plexus
what is the bodys primary communication and regulation system
nervous system
what does the somatic nervous system control ?
seeing, hearing, taste, smell, and touch
what is the most common neurotransmitter and what is it needed it for
acetylcholine, needed for muscle control
what is the difference between Afferent and efferent in regards to the CNS
Afferent transmits impulses towards the CNS
Efferent transmits impulses away from the CNS
what maintains the bodies circadian rhythm (sleep wake cycle)
pineal gland
what are the basic structures of the nervous system
brain, spinal cord, cranial and spinal nerves, sense organs, neurotransmitters
what controls energy conservation
parasympathetic division
what is secretion
ability to release a chemical called neurotransmitter
what neurotransmitter is found in the brain and ANS
Dopamine
what are the layers of the meningal layers in order from deep to superficial
1- pia mater (Deep) 2- Arachnoid mater (Middle) 3- Dura mater (Superficial)
name at least 2 functions of the nervous system
1- sensory input 2- interpretive functions 3- motor output 4- higher mental functioning/ cognition
what does the autonomic nervous system regulate
invoulentary activities of organs, glands and smooth muscles
what are the 3 basic parts of a neuron
cell body, dendrite, and axon
whats included in the Diencephalon
the thalamus, hypothalamus , pituitary gland, and pineal gland
what are the bundles of transverse fibers called that the 2 hemisphears communicate with eachother
Corpus Callosum
what is the difference between the nervous system and the endocrine system
nervous system responds more rapidly, and uses neurotransmitters as chemical messengers and impulses to transmit info along nerve cells
what is the exception of what the ANS regulates
breathing
what are the "decision making neurons"
interneurons
what are bundles of myelinated axons called
White matter
best brain wave pattern for studying
GAMMA
