Front 1

type of control in cardiac muscle tissue

Back 1

involuntary

Front 2

smooth muscle tissue

Back 2

1) found in digestive tract, arteries.
2) shape like a spindle, unstriated
3)uninucleate, nuclei are long and elongated.

Front 3

Function

Back 3

skeletal- moves the bones
cardiac- pumps blood
smooth- move contents within an organ.

Front 4

Nervous tissue

Back 4

cell body- carries on function for the cell.
dendrite- receives nerve impulses, short and numerous
Axon- carries impulses to brain and spinal cord.

Front 5

Neuron

Back 5

Cellular constituent in nervous system.

Function- senses and responds to stimuli in environment. relays information

Front 6

Epidermis

Back 6

First skin layer has two cell types: keratinocytes and melanocytes

Front 7

Keratinocytes

Back 7

secrete a tough, water insoluble protein.

Front 8

Melanocytes

Back 8

produce a brownish black pigment called melanin, which filters out ultraviolet radiation from sunlight.

Front 9

Dermis

Back 9

Second layer of skin.
Middle and thickest layer.
Contains sweat glands, sebaceous glands and many blood vessels.

Contains hair follicles and nerve endings.

Front 10

Subcutaneous layer

Back 10

The deepest layer of skin.
Insulates body.
Provides protective padding.
Stores energy here. (Has much adipose (fatty) tissue here)

Front 11

Aging effects on skin

Back 11

1. loses elasticity because of water loss and fat loss.
2. melanocytes decrease.
3. blood vessels decrease.

Front 12

Functions of skin

Back 12

1) barrier to moisture loss
2) protection

Front 13

Types of skeletons

Back 13

1) hydrostatic- muscles work
2) endoskeleton- rigid internal body
3)exoskeleton- rigid external body parts

Front 14

Skeletal system

Back 14

Appendicular- consists of bones of the appendages and the bones that link the appendages to the axial skeleton

Front 15

Pectoral Girdle contains:

Back 15

1) clavicle (collar bone)
2) scapula (shoulder blade)

Front 16

Bones coming off pectoral girdle

Back 16

a) humerous-funny bone
b) radius
c) ulna (looks like monkey wrench)
d)carpals (wrist)
e) metacarpals (main hand)
f) phalanges (fingers)

Front 17

Pelvic Girdle

Back 17

-formed by the coxal bones,
which consists of three bones:
1) ileum-upper portion
2)ishium-central portion
3)pubis- bottom portion

Front 18

Bones coming off pelvic girdle

Back 18

femur
petella
tibia (big bone in lower leg)
fibula- small bone in lower leg
tarsal- ankle
metatarsal-main part of foot
phalanges

Front 19

axial skeleton

Back 19

skull-protects brain
vertebral column-protects spinal cord
ribs and sternum-protects heart and lungs

Front 20

Ball and socket joint

Back 20

allows movement in all directions (shoulder, hip)

Front 21

Hinge joints

Back 21

1) one way movement (fingers and toes)

Front 22

Pivot Joints

Back 22

allow bones to rotate, provide ease of manipulation. (wrists and hands)

Front 23

yellow bone marrow

Back 23

stores fat

Front 24

spongy bone

Back 24

1. found in the end of the bone
2. honeycomb like with small cavities
3.contains red bone marrow

Front 25

Skeletal disorders

Back 25

1. Arthiritis- inflammation of joiints
2. osteoarthritis-joints become stiff, cartilidge is worn.
3. rheumatoid-autoimmune disease
4. Osteoporosis- bones become thinner.

Front 26

Prevention for skeletal disorders

Back 26

1) sufficient calcium intake
2) weight bearing excersize
3) don't smoke

Front 27

Skeletal Muscles

Back 27

attached to skeleton and produces body movements.

Front 28

Trapezius

Back 28

upper portion of back, triangular

elevates shoulder.

Front 29

Latissimus Dorsi

Back 29

lower portion of back

help with deep inspirations

Front 30

Rectus Abdominus

Back 30

in the abs, usage is heavy during sit ups.

Front 31

Deltoid

Back 31

forms rounded muscular area over the shoulder.

abducts the shoulder joint.

Front 32

External obliques

Back 32

side of the trunk

supports abdominal muscles.

Front 33

gastrocnemius

Back 33

calves

flexes knees and foot.
