4 major types of tissues

1. Epithelial Tissue

2. Connective Tissue

3. Muscle Tissue

4. Nervous Tissue

Epithelial Tissue (Func, structure, shapes, classificaion)

FUNC: cover and line other tissues and organs to protect them

STRUC: types are named by the shape and number of cells in the tissue

SHAPES: Squamous, Cuboidal, Columnar

# CLASSIFICATION: Simple, Stratified, Pseudostratified, Transitional

EX: Skin (stratified squamous)

Squamous

Cuboidal

Columnar

Simple

Stratified

Pseudostratified

Transitional

Connective Tissue (Function, Types)

FUNC: Bind and support other structures

TYPES: Loose Connective Tissue, Fibrous Connective Tissue, Adipose Tissue, Cartilage, Bone, Blood

Loose Connective Tissue

Fibrous Connenctive Tissue

Adipose Tissue

Cartilage

Bone

Blood

Muscle Tissue (Funciton, Types)

FUNC: Contract and generate force which can prodice pvement and other functions

TYPES: Skeletal, Smooth, Cardiac

Skeletal

Smooth

Cardiac

Nervous Tissue (Function, Structure, Types)

FUNC: Senses stimuli (5 senses) and transmits information (EX: feeling it’s cold outside (sensing) —> getting a jacket (transmitting ))

STRUC: made of neurons

TYPES: Motor Neurons, Sensory Neurons, Interneurons

parts of a Neuron (7 terms)

Dendrites, Soma, Nucleus, Axon, Myelin Sheath (w/ Schwann Cell), Nerve ending

Motor Neurons

Sensory Neurons

Interneurons
