DSA Week 3:

Simple Squamous Epithelial

absorbtion, secretion, filtration in alveoli, glomeruli

Simple Cuboidal Epithelial

Function: absorbtion, secretion

Location: glands, ureters

Simple Columnar Epithelial

Function: absorbtion, secretion, associated with mucus-secreting cells

Location: Digestive tract

Pseudostratified Columnar Epithelial

Function: secretion, propulsion

Location: respiratory tract

Stratified Squamous Epithelial

Function: protection

Location: outside of skin

Stratified Cuboidal Epithelial

Function: protection, secretion

Location: ducts of glands

Stratified Columnar Epithelial

Function: protection, secretion

Location: pharynx, urethra, glandular ducts, transition areas or junctions

Transitional Epithelial

Function: stretches

Location: lining of hollow urinary organs

Areolar Connective

universal packing material

Adipose Connective

stores energy, insulates the body

Reticular Connective

internal framework that supports immune cells

Dense Regular Connective

makes up tendons that attach muscles to bone

Dense Irregular Connective

providing strength and flexibility in multiple directions, found in the dermis of the skin and organ capsules

Elastic Connective

allows the tissues to recoil after stretching, found around vertebrate, blood vessel walls and bronchial tubes

Hyaline Cartilage

Function: strong support and shock absorbtion

Location: tip of the nose, connects the ribs to the sternum

Elastic Cartilage

Function: maintains structure and allows flexibility

Location: outer ear and epiglottis

Fibrocartilage

Function: compressible and resists tension

Location: intervertebral discs and knee

Osseous

supports the body structure, stores calcium and fat, marrow inside bone makes blood cells

Blood

Function: transports stuff in and out

Skeletal Muscle Tissue

multinucleated, striated muscle fibres, voluntary movement

Smooth Muscle Tissue

spindle-shaped, no striation, uni-nucleated, involuntary movement

Cardiac Muscle Tissue

branched and striated muscle fibres, electrically couple via intercalated discs, pumps blood

Neurons

basic unit of nervous tissue, sense stimuli and transmit impulses around the body

Neuroglial Cells

support nerve cells: supply nutrients to neurons, removes excess neurotransmitters, maintains electrolyte balance, nervous system repair, protection against microorganisms

Astrocytes

Function: form a blood brain barrier

Location: brain + spinal chord

Schwann Cells

Function: forms the myelin sheath

Repair

proliferation of cells + tissue + scar tissue (function not fully restored)

Restoration

proliferation of cells and tissue (complete restoration of lost structure)
