A&P Unit 3 Lab (functions)

Protects spinal cord

protects spinal cord

protects spinal cord

stabilizes the spinal cord

connects dura mater to pia mater

anchors conus medullaris

gives rise to brachial plexus

gives rise to lumbar plexus

send & receive messages to & from lower limbs/pelvic organs

carry sensory neural signals to CNS (afferent)

carry motor neural signals away from the CNS (efferent)

convey info from external or internal sites of body; relay sensory nerve impulses to PNS

split between right & left halves where spinal artery sits

divide spinal cord in half

carry motor neuron information

carries neurons from the sympathetic nervous system

carries sensory information

connect left & right halves of grey matter allowing for communication

carries CSF

carry sensory information up to the brain

carry visceral/somatic motor & sensory info to & from the skin * deep muscles of the back

carry visceral/somatic & motor info to & from the ventrolateral body surface

allows nerve fibers to travel to other spinal nerves

nerve fibers that run from the skull to the coccyx

innervates the abdomen

arise from within the sympathetic trunk

innervates diaphragm

emotion control & decision making

taste & language

hearing, smell

vision

increase surface area

increase surface area

separates hemispheres

high level of thinking

"mountains" ; increase total area

"valleys"; increase area

communication between hemisphere

relay center, filters important information

autonomic effects & hormone regulation & circadian rhythm regulation

connection

hormone maintenance

connect limbic system to other parts of brain

secretes melatonin

CSF production

memory

afferent & efferent signaling

equilibrium, motor coordination, memory of learned motor skills

incompletely divides left & right cerebellum

sleeping, dreaming

contains cardiac & respiratory centers, cough/sneeze/vomit reflex

visual & auditory reflex

vision reflex

auditory reflex

allows blood to leave & CSF to enter

house arachnoid space

supply brain tissue with blood

contain csf

send & receive info from lateral ventricles

protect brain from trauma

connect lateral ventricle to third ventricle

allows csf to flow between 3rd & 4th ventricle

smell; test function with strong aroma's

vision; text with range of vision

eye movement; test ability to track movement

superior oblique eye movement; bielschowsky's head tilt test

touch & pain sensation; pinch test

movement of lateral rectus muscle of eye; follow finger toward nose test

facial movement, taste, touch; lift eyebrows/smile test

hearing & balance; standing on one foot test

taste & swallowing; gag reflex

parasympathetic functions; say ahh, check body response to reflex

neck & shoulder movement; shrugging test

tongue movemnt; tongue movement test

protection, secretion, sensation, heat regulation, excretion, absorption

cells from which all other cells with specialized functions are derived

most common type of skin cell, make up structural component of epidermis

in the stratum basale layer and provide pigmentation and protection from UV radiation

send messages to brain when feeling sensations of hot, cold, pain

immune cells; initiate all antigen-specific immune responses

multiple layers of "dead" scaley keratinized cells

only found in THICK skin of palm, heels, and digits

multiple layers of flat keratin

several layers of keratinocytes, desmosomes, and tight junctions; allows for shape and water retention

compose of cuboidal stem cells/keratinocytes that migrate to surface to replace lost cells

regenerate the cycling portion of the hair follicle and generate the hair shaft

ridges in the overlying epidermis; "finger prints"

made up of areolar CT, vascularity, tactile cells
