tissues and systems

what are the 4 different tissue types

o Epithelial

o Connective

o Muscular

o Nervous

Tissue

aggregate (group) of cells of same type with

functional unity

Epithelial

skin layers, lining cavities(to hold moisture), may be secreting epithelium, may be ciliated

simple epithelium

a single layer of cells

Ciliated epithelium:

cylindrical cells with cilia examples Lining of nasal cavity, larynx,

trachea, bronchi

Stratified epithelium

flattened cells on columnar cell bed examples Epidermis of skin, lining of mouth, pharynx, esophagus

connective tissue (major types)

Adipose, Dense fibrous: tendon, aponeurosis, ligament, fascia, Cartilage, Bones

adipose

fat cells

yellow elastic

elastic in areas requiring recoil such as cartilage of trachea, larynx, bronchi

Hyaline cartilage

Bluish-white; on articulating surfaces of bones and cartilage; ribs, larynx, trachea

Fibrocartilage

Dense, white, flexible; intervertebral disks, knees

Yellow (elastic) cartilage

Firm; pinna, epiglottis

MUSCULAR TISSUE types

Striated (skeletal, voluntary, somatic)

Smooth (involuntary, autonomic)

Cardiac

VISCERAL MUSCLE (smooth muscle)

involuntary function (examples glands, organgs, digestions)

stomatic muscle

voluntary movement

cardiac muscles

heart muscles

what are muscles made of and their function

fibers and all muscles can do is contract

fast twitch muscle fibers

contract quickly are fatigued easliy

slow muscle twitch fibers

built for larger movements they are slower but have more endurance

Origin

The point of attachment of a muscle that is relatively immobile during contraction

Insertion:

Insertion: The point of attachment of a muscle that is relatively mobile during contraction

Agonist:

The muscle that performs the intended action (prime mover)

Antagonist:

A muscle that opposes the intended action

systems of speech

Resonatory

Phonatory

Respirator
