A group of similar cells that usually have a common embryonic origin and function to carry out specialized activities

• 1. Epithelial Tissue
• 2. Connective Tissue
• 3.Muscle Tissue
• 4. Nervous Tissue

• 1. Covers body surfaces
•               a) organs, cavities and ducts

2. Forms glands

1. Protects, supports and holds body together

2. Stores energy and minerals

3. Immunity

1. It facilitates physical movement

• 2. 3 types
•        1. Skeletal Muscle
•        2. Cardiac Muscle
•        3. Smooth Muscle

• 1. Detects, monitors and responds to stimuli
• 2. Produces action potential
• 3. Creates responsivess

• A. Closely packed cells held tightly together
•        1. tight junctions between cells
•        2. little extracellular "stuff"
• B. Arranged in sheets
•        1 Can be
•               a. single layer
•               b. multiple layers

• A. two characteristics
•      1. cell shapes (3 shapes)
•           a. flat-squamos
•           b. cube shaped-cuboidal
•           c. column like-columnar
•           d. transitional -can change shape
•      2. layers of cells (3 basic systems)
•           a. single layer-simple
•           b. multi-layered-stratified
•           c. looks multi-layered but its not- peudostratified

A. Most abundant tissue in the body

• B. Consists of two elements
•      1. Cells
•                 a. few of them
•                 b. several kinds
•     2. Matrix 
•                a. makes up mos of tissue

Space between skull bones at birth, filled with connective tissue

An opening though which blood vessels, nerves or ligaments pass through

A fossa is a trench, shallow depressions in or on a bone

A meatus is a passageway- a channel though bone

1. Condyle-large knucle-like process at the end of the bone

2. Head-rounded end of a bone

1. Spinous Process-spince

2. Tuberosity-large rounded, roughened process

1. Ligaments-connective tissue that holds two bones together

2. Tendon-connective tissue that attaches muscle to bone

3. Cartilage-rubbery-like substance that cover the ends of bones forming a joint, it provides cushioing and reduces friction that would destroy the bone.

1. Axial skeleton-has 80 bones

2. Appendicular skeleton- has 126 bones

Areolar Connective tissue

Adiopose Connective tissue

This is Hyaline connective tissue

This is Bone connective tissue

This is Dense regular connective tissue
