Week 1 Flashcards
anatomical position
person erect, flat feet on floor, arms at side, palms, face, and eyes forward
when referring to body movement or location what do you use
anatomical position, not the actual position the body is in
anatomical planes
sagittal
medial
coronal
transverse
sagittal plane
from side to side, vertical line
medial plane
middle of body, bilateral
coronal plane
front and back,
transverse plane
up and down
superficial
near surface
intermediate
between superficial and deep
deep
further from surface
example of superficial, intermediate, and deep structures
skin, muscle, bone
medial
nearer to median plane
lateral
farther from median plane
examples of medial and lateral
nose, eyes
pinky, thumb
proximal
closer to the beginning of structure, closer to body
distal
farther from beginning of structure, further from body
example of proximal and distal
knee, foot
superior (cranial)
closer to head
inferior (caudal
closer to feet
example of superior and inferior
head, chest
anterior (ventral)
front
posterior (dordal
back
body systems
tissues and organs that operate together to perform specific functions
integumentary system (skin)
complex layered organ that mostly fulfills obligations dealing with keeping stuff we want in and stuff we want out
layers of skin
epidermis
dermis
subcutaneous tissue
deep fasica
muscle
bone
epidermis
living and dead skin cells
dermis
supporting tissue for epidermis
subcutaneous tissue
“Sub Q”, fatty tissue over muscle
deep fascia
connective tissue over muscle
skinning
cut down to deep fascia and leave it on muscle
muscloskeletal
axial
appendicular
axial
head, vertebral column, and ribs
appendicular
legs, arms, scapula, clavicle, hip bones
types of muscle
skeletal
smooth
cardiac
skeletal muscle
conscious movment
smooth muscle
unconscious movement
cardiac muscle
unconscious movement
nervous system
central nervous system
peripheral nervous system
central nervous system
brain and spinal cord
peripheral nervous system
nerves connecting CNS to rest of body
dermatome
skin innervated by a spinal segment
myotome
muscle innervated by spinal segment
vasculature
carries blood and other materials to different parts of the body
arteries
carry blood away from the heart, usually oxygenated
vein
carry blood towards heart, usually not oxygenated
what color are arteries typically depicted
red
what color are veins typically depicted
blue
characteristics of arteries
thicker, less elastic, under greater pressure, found deeper in tissue
characteristics of veins
flimsy, deflated in cadavers, have less pressure, and are found superficial
lymphatics
picking up fluid that has been lost from blood vessels and recycling it back into cardiovascular system
essential in immune system
how do muscle create movement
contracting
joints
where 2 bones meet, where motion happens
synovial joints
designed to allow movment
joint capsule
protects and lubricates joint during movement
ligament
connects bone to bone
tendon
connects muscle to bone
flexion
decrease angle of joint, move anteriorly
extension
increase angle of joint, move poseriorly
hyperextention
moving past 180 degrees in extension
abduction
moving away from body or each other
adduction
moving toward body or each other
supination
movement of arms to palm forward
pronation
movement of arms to palm backwards
rotation
lateral or medial
what limits joints?
muscle, bone, ligaments,
