UMSL TEST Flashcards
a lowered body temperature
hypothermia
type of intercellular junctions that forms channels through which cytoplasm can flow
gap junctions
type of intercellular junction that acts as a river or spot weld
desmosomes
lipid portions of two membranes tightly bound by interlocking membrane protein
tight junctions
study of tissues
histology
four basic body tissue types
epithelial
connective
muscle
neural
type of epithelium that lines the urinary bladder
transitional
produce connective tissue fibers
fibroblasts
produce bone tissue
osteoblasts
tendons and ligaments are composed primarily of what type of tissue
connective (white)
lines tubes and cavities that open to the outside of the body
mucous membrane
“cutaneous membrane” refers to
skin
the human integumentary system includes
skin, nails, follicles, sweat glands
sebaceous glands secrete __________ aka __________
fat globules that mix with cellular debris
sebum
blood vessels in the _____ supply epidermal cells with nutrients
dermis
what determines the color of skin
amount of melanin that melanocytes produce
shafts of hair are composed of
dead epidermal cells
a nail consists of
nail bed, nail plate
1st degree burn
skin is red
2nd degree burn
blistered
3rd degree burn
deep tissue/nerve damage
in treating burn patients, the rule of nines is used to estimate
surface area of the burn
exposure to ultraviolet radiation greatly increases the risk of developing
skin cancer, cataracts
list the functions of the skeletal system
provides support for muscles
stores inorganic salts
protects organs
vitamin D deficiency results in
rickets
vitamin A deficiency results in
retardation of bone development
the axial skeleton includes
skull
hyoid
thorads
vertebral
the appendicular skeleton includes
upper/lower limbs
ribs that join the sternum directly by costal cartilages
true ribs
ribs that join indirectly or not at all
false ribs
ribs that connect only at one end
floating ribs
a depression in the hip bone for the femur
acetabulum
joints are also called
articulations
joints function to
bind bones
allow bones to grow
enable movement
classifying joints as synarthrotic, amphiarthrotic, or diarthrotic is determined by
degree of movement
types of fibrous joints
syndesmosis
suture
gomphosis
a tooth attached to a jawbone by a periodontal ligament is a
gomphosis joint
movement that brings the foot father from the shin
plantar flexion
movements permitted by the elbow joint between the humerus and ulna
flexion & extension
fluid-filled sacs containing synovial fluid
bursae
the coracohumeral ligament is found in the ________ joint
shoulder
ankle and wrist joints are what type of joints
plane
joint types that allow rotation
saddle
ball-and-socket
three types of muscle cells
skeletal
cardiac
smooth
a muscle end attached to a less movable or relatively fixed part
origin
the muscle tissue that can be consciously controlled
voluntary (skeletal)
eccrine glands are found in the _____ and function to __________
skin
regulate body temp (sweat)
the arrector pili muscle is attached to __________ and causes ____________
a hair follicle
hairs to stand up
in the inherited disease ichythyosis, the skin is rough, brown, and very scaly because the uppermost layer cannot peel off as easily as it normally does. the part of the skin affected is
epidermis
first and second degree burns are also called _________ because _____________
superficial
surface is affected
inflammation causes
red, swollen, painful to touch skin
osteoblasts are what type of cell
bone-forming cells
osteocytes are what type of cell
mature bone cells
long bones include
forearm, lower leg
short bones include
wrist/ankle
flat bones include
skull
irregular bones are
vertebrae
a bone lengthens by
increased activity of the epiphyseal plate
the atlas and axis are what type of vertebrae
cervical
phalanges are found in the
fingers and toes
the talus, calcaneus, navicular, cuboid, and cuneiform bones are all part of the
foot
list ways which a female’s skeleton is different from a male’s skeleton
female pelvis is wider, lighter bones overall
the largest and most complex synovial joint is the
knee joint
the most movable joint is the
shoulder
what effect do sex hormones have on bone growth, osteoblasts, and the epiphyseal plate?
stimulate ossification of epiphyseal plates
