Review Epithelial Tissue Cards

What is the most abundant tissues in the body?

Connective tissue

What are the functions of connective tissue (5)?

binding
support

protection

insulation

transportation

How many types of connective tissues are there?

6

Adipose
Loose connective

Dense Regular

Cartilage

Bone/ Osseous

Blood

Adipose Tissue

Function and Location

it is closely packed fat cells

reserve food fuel, protects organs, and insulates against heat loss

Found under skin, breast, abdomen

Dense Regular

Function and Location

parallel collagen fibers w/ fibroblasts

attaches muscle to bones and bones to bones, withstands great tensile strength

found in tendons and ligaments

Cartilage

Three types

Function and Location

Hyaline:

supports and has cushioning properties

found in joints, nose

Fibrocartilage:

tensile strength, absorbs compressive shock

found in vertebral discs, knee discs

Elastic:

maintains shapes of structure. allows flexibility

found in external ear

Bone Osseous

Function and Location

hard calcified matrix

bone supports and protects, act as levers for muscles, marrow is site of blood formation

found in bones

Blood

Function and Location

red and white blood cells in a fluid matrix

transports respiratory gases, nutrients, waste

found in blood vessels

Nervous Tissue

Function and Location

made of neurons and neuroglia

transmits electrical signals from sensory receptors and effectors (glands/ muscles)

found in brain, spinal cord, nerves

What are the three types of muscle tissue?

Skeletal, smooth, cardiac

Skeletal

Desc Function, Location

long cylindrical, multinucleate, striations

voluntary movement, control facial expressions

found in skeletal muscles attached to bones or skin

Smooth

Desc, Function, Location

(4 sentences)

spindle shaped cells, central nuclei, no striations, form sheets

propels substances (urine, food, baby) along internal passageways

involuntary movement

found in walls of hollow organs (stomach, large intestine)

Cardiac

Desc, Function, Location

branching, striated, unicellular, form intercalated discs

propels blood into circulation, involuntary

found in walls of heart

What are the 4 types of epithelial membranes?
Hint: C, S, M, S

1. Cutaneous:

   skin

2. Synovial:

   line joint cavities (skeletal)

3. Mucous:

   line body cavities OPEN to exterior (digestive: mouth) (respiratory: nose)

4. Serous:

   moist membranes line cavities CLOSED to exterior

   Ex: abdominal, thoracic, cranial
