spinal cord and brain Flashcards
mnemonic to remember spinal cord function
DAVE
Dorsal= afferent
Ventral= efferent
conscious thought, voluntary movt
-the big part of brain
cerebrum
contains thalamus and hypothalamus
sensory relay, autonomic control
-lies between he midbrain and cerebrum
diencephalon
contains midbrain, pons, medulla
reflexes, vital functions (breathing and HR)
brainstem
coordination, balance, fine motor control
cerebellum
mnemonic for the major brain division
Cats Do Big Chores
mnemonic for cerebrum lobes
Funny People Think Outloud
which lobe? think, plan, motor control, speech
frontal
Front= focus (thinking)
which lobe? tough, spatial awareness
parietal
parietal= pressure (touch)
which lobe? hearing, memory, speech
temporal
tempo=temporal (hearing)
which lobe? vision
occipital
ocular=occipital=eyesight
mnemonic for diencephalon function
T for Traffic (thalamus= sensory relay)
H for Home (hypothalamus= homeostasis)
what is sensory relay station (except for smell)
thalamus
what is used for homeostasis, hunger, hormones
hypothalamus
mnemonic for brainstem and functions
MPM
Midbrain-moves eyes
Pons-Passes info
Medulla-Maintains life
what controls reflexes and eye movts
midbrain
what controls the communication btwn brain regions
pons
controls breathing, heart rate, BP
medulla
“little brain”
cerebellum
what carries sensory
posterior/dorsal
what carries motor
anterior/ ventral
carry sensory signals (afferent) to spinal cord
location- posterior, connects to dorsal horn
dorsal root
carry motor signals (efferent) to muscles
location- anterior side, connects to ventral horn
ventral root
-ventral= vehicle (motor)
cluster of sensory neuron cell bodies
location- buldge on dorsal root
-gang of sensory neurons
dorsal root ganglion (DRG)
shallow groove seperating left and right spinal cord
location- posterior midline
posterior median sulcus
-sulcus=shallow
deep groove helping seperate left and right spinal cord
location- anterior midline
anterior median fissure
-fissure= f*ing deep
contains cerebrospinal fluid for nourishment
location-middle of spinal cord
central canal
-central=csf flow
connects left/ right gray matter
location- surrounds central canal
gray commissure
-gray=bridge
process sensory info (touch. pain)
location- back wings of gray matter
posterior gray horn
posterior=pain processing
controls autonomic funtions
location- sides of gray matter
lateral gray horn
-lateral=life functions
motor neurons for voluntary movt
location- front wings of gray matter
anterior gray horn
-anterior=action (motor)
sends sensory info to brain
location- back of white matter
posterior white column
-white=wiring
allow left/ right spinal cord communication
location- front of white matter near fissure
anterior white commissure
-commissure=communication
What is the functions of the diencephalon region of the brain?
Responsible for sensory processing, autonomic, control, and hormone regulation
Responsible for process and transmitting sensory information, except smell, to cerebral cortex. It functions in motor control, consciousness, alertness, and sleep regulation.
Thalamus
Functions in maintaining homeostasis by regulating body temperature, hunger and thirst. For the autonomic nervous system it regulates heart rate, blood pressure and digestion. In the endocrine system, it regulates by releasing hormones that control the pituitary gland. It also controls emotion and behavior.
Hypothalamus
Connect the limbic system to other parts of the brain. It regulates emotions, memory responses to odors. It contains the pineal gland.
Epithalamus
What functions in secreting melatonin. Response to light and darkness.
The pineal gland
Controls other endocrine glands
Pituitary gland
communication between hypothalamus and pituitary gland. transmit hormone signals that regulate body functions like stress, growth, water balance, and reproductive
