Term
Name the 4 types of tissue
Definition
1. Epithelial Tissue
2. Muscle tissue
3. Nervous=Neural Tissue
4. Connective Tissue
Term
Epithelial Tissue
Definition
(Endothelium in cardiovascular system)
Very cellular, avascular, protects, sensory, glands, permeability

Ex:outer layer of the skin (epidermis), the lining of the digestive and respiratory tracts
Term
Muscle Tissue
Definition
Capable of contraction

Ex: where skeleton attaches, heart primarily made of muscle
most of your muscles in viscera
Term
Nervous/Neural Tissue
Definition
Control and communication (Neutrons)
Term
Connective Tissue
Definition
Most Common (blood and Fat)

Most abundant tissue in the body
Framework, structural, surrounds, connects, transports, protects, storage
Ex. bone, cartilage, tendons, ligaments, blood and fat
Term
Cells
Definition
Fibroblasts are the most abundant fixed connective tissue cells and produce and maintain fibers and ground substance. other cells could (depending on the type of connective tissue) be adipose cells, osteocytes, chondrocytes, or blood cells
Term
Intercellular matrix
Definition
A) Ground Substance
B) Fibers
Term
Ground Substance
Definition
Fluid to semisolid homogeneous background made by the connective tissue cells
Term
Fibers
Definition
1. Collagen
2 Elastic
3. Reticular
Term
Collagen
Definition
Rope like, strong protein fibers
Big strong ropes

Most common
Term
Elastic
Definition
stretchy fibers such as those in the vocal cords
Term
Reticular
Definition
Short and thin fibers such as those of the spleen, liver, and lymph nodes
Mesh Like
Term
Explain how epithelium and connective tissue combine to form 4 different types of membranes.
Definition
Somewhere in between tissue and organ the. They are barriers that cover or protect
Term
Mucous Membrane
Definition
membranes, moist with mucus, that line cavities such as the oral and nasal cavities
Term
Serous Membranes
Definition
permeable membranes that are moist with a watery fluid found lining the thoracic and abdominal cavities
Term
Cutaneous Membrane
Definition
Top two layers of Skin
Term
Synovial Membranes
Definition
Line the joint vacuities and produce synovial fluid
