Unit 3- Nervous System Flashcards
Parasympathetic nervous system
Rest and digestion
Somatic nervous system
Voluntary system, control skeletal muscles
Autonomic nervous system
The sympathetic and parasympathetic nervous system
Cervical vertebrae
Arms and shoulders
8 segments
Thoracic vertebrae
Controls upper body and inner arms
12 segments
Lumbar segments
Controls legs and hips
5 segments
Sacral segments
Controls genitalia and lower calves and ankles
4 segments
Pneumatic for vertebrae segments
Certainly Thor loves sandwiches
Vagus nerve
Motor and sensory
Gag reflex, parasympathetic innervation
Vestibulocochlear
Sensory
Hearing and balance
Trochlear
Motor
Moves eyes
Olfactory verves
Smell
Optic nerve
Sensory
Vision
Olculomotor
Motor
Most eye movement
Trigeminal nerve
Sensory and motor
Face sensations, mastication
Facial nerves
Motor and sensory
Facial expression and taste
Glossopharyngeal nerve
Motor and sensory
Taste and gag reflexes
Hypoglossal nerve
Motor
Swallowing and speech
Abducens nerve
Motor
Abducts the eye
Spinal accessory nerve
Motor nerves
Shoulder shrug
The 12 cranial nerves pneumatic
Victor Vance the old ostrich observed the fat giraffe Henry acting scared
Cerebellum
Coordination of motor output
Medulla
Controls respiration and autonomic function
Controls neurons that receive and relay functional information
Pituitary
Controls the endocrine system by producing important hormones
Tectum
Receives inputs from visual, tactile and auditory inputs
Pons
Interconnect of the forebrain and the cerebellum. Controls sleep, equilibrium, taste, facial expressions and sensations
Amygdala
Processes input and organizes output
Emotions
Thalamus
Relay of sensory input and does some processing
Cerebral cortex
Outer layer of the cerebellum, does processing and higher brain function
Hypothalamus
Controls body temp, eating, drinking and sex
Pneumatic for parts of the brain
CMPT PATCH
Sympathetic nervous system
Fight or flight
key parts of all the BRAINSSSSSS
cerebrum, cerebellum, medulla, olfactory bulb, pituitary
fish brains
-opitc lobe and olfactory tract
Frog brain
optic lobe, optic tract, epiphysis
bird brains
YOU
optic lobe, epiphysis
human
pons, hypothalamus, anterior commissure, thalamus, corpus colosum, occipital lobe, optic chiasm, cerebral hemisphere
big picture neural developments
-neural tube, primary vesicles, secondary vesicels, adult structures
final result of the vertebrate brain development
forebrain= cerebellum, thalamus, hypothalamus
midbrain- tectum
hindbrain- Pons, Cerebellum, medulla oblongata
Name the 6 regions of teh mammalian cortex
- visual, auditory, somatosensory, olfactory, association, motor
- viscous acronyms sometimes offer aid mentally
What are the 5 main areas on which teh parasympathetic and sympathetic nervous systems work on?
- HODGE
- heart rate
- oxygenation of blood
- dialation of pupils
- glucose levels in the blood
- epinepherine and norepinephrine
sympathetic increase
parasympathetic decrease
Which neurotransmitters are used in the preganglionic neurons of the sympathetic NS
acetylcholine
which NTMs are used in the post ganglionic neuron of Sympathetic NS
norepinephrin
which NTMs are used in the preganlionic neurons int eh parasympathetic NS
acetylcholine
which NTMs are used in the postcanclionic neurons int eh parasympathetic NS
acetylcholine
