Neuron and CNS anatomy: brain and spinal cord structures
Karten in diesem Stapel (48)
- 1Axon-"Talker" of a neuron; a long process that may or may be covered in myelin
-Talks to other neurons at the dendrites - 2Node of Ranvier-Gap between segments of myelin on axon
-Where ion channels are within myelinated axons - 3Dendrite-"Listener"
-Shorter extensions/processes that receive information from another neuron from the environment - 4Myelin-Wrapping of the axon
-Protective covering of SOME axons
-Increases the speed in which the electrical signal can travel within a neuron - 5Axon HillockWhere action potentials are initiated
- 6Axon TerminalThe end of a neuron where
neurotransmitters are released - 7Cell BodyWhere the nucleus is housed within a neuron
- 8Spinal Nerve (Parts of the spinal cord)Mixed nerve containing sensory and motor nerves
- 9Dura MaterOuter fiberous membrane of the spinal cord and brain
- 10Pia MaterInnermost thin membrane covering the surface of the spinal cord and brain
- 11Arachnoid MaterMiddle membrane covering of the spinal cord and brain
- 12Spinous ProcessThe posterior part of the spinal vertebra
- 13Vertebral BodyThick part of the vertebrae which stacks on top of other vertebrae
- 14Dorsal Root Ganglion-Contains sensory neuron cell bodies
-Enlargement of the root - 15Dorsal HornSensory area within the grey matter of the spinal cord
- 16Ventral HornMotor area within the grey matter of the spinal cord
- 17Dorsal Root-Sensory "writing" attached to the spinal cord
-Sensory neuron axons carrying sensory info INTO spinal cord - 18Ventral Root-Motor "wiring" attached to the spinal cord
-Motor neuron axons carrying motor commands OUT of the spinal cord - 19Epidural SpaceSpace between the periosteum of the vertebra and the dura mater
- 20PeriosteumThin layer of connective tissue that covers surface of bones
- 21White MatterMyelinated nerve fibers in CNS
- 22Grey Matter-"H" shaped
-Contains dorsal and ventral horns - 23Cerebrum-Largest part in brain
-Left and right hemisphere of brain - 24Cerebral Cortex-Outer most layer of cerebrum
-4 lobes
-Rigid part of brain
-Contains grey matter - 25Temporal LobeSide part of brain
- 26Occipital LobeBack part of brain
- 27Frontal LobeFront part of brain
- 28Parietal LobeTop part of brain
- 29VentricleCavity or space in brain that is filled with cerebrospinal fluid (CFS)
-4 ventricles in brain - 30Choroid PlexusProduces cerebrospinal fluid (CFS) in ventricles
- 31Corpus Callosum-Translates info between left and right hemisphere
-Largest white matter in brain - 32Thalamus-Sensory relay station
-Decides where to send or not send the signals it receives except smell
-Top of brain stem between cerebral cortex and midbrain - 33Hypothalamus-Below Thalamus
-Controls pituitary gland
-Regulates hunger, thirst and temp (ANS) - 34Epithalamus (Pineal Gland)-Next to thalamus
-Releases melatonin when light dims - 35Midbrain-Auditory & visual reflex center
-Located at top of brain stem - 36Pons-Under Midbrain
-Passes signals up and down
-Connects brain to cerebellum
-Begins REM sleep and disconnects - 37Medulla Oblongata-Passes signals up and down
-Connects brain to spinal cord
-Most important
-Basic life support
-Mid spinal cord next to cerebellum - 38Cerebellum-Coordination of movements
-Behind brain stem (wirery looking)
-Alcohol impairs cerebellum - 39Pituitary Gland-Pea sized gland at base of brain
-Below hypothalamus within sella tercia - 40Motor CortexLeft-Right
Right-Left
-Center of brain - 41Sensory Cortex-Parietal lobe
-Processes sensory info - 42Sensory Association Area-Tells you what you are touching
-Adjacent to sensory cortex - 43Premotor Cortex-Plans motor movements
-Frontal lobe - 44Prefrontal Cortex-Complex thoughts
-Personality
