basic unit of human life
cell
- group of cells that have a common function
- five basic types of tissue with subordinate groups within each type
- categorized by differing amounts and kinds of intercellular material and different shapes of cells
tissues
tissues are categorized by
differing amounts and kinds of intercellular material and different shapes of cells
elementary tissues
- Epithelial
- connective
- muscle
- nervous
- vascular
sheets of cells resting on a collagen-based membranous surface
epithelial tissue
where is epithelial tissue at?
- skin
- glandular
- lining of body cavities
- cilia
bind and support various structures in the body. mostly intercellular matrix of various kinds within which are the cells
connective tissue
mix of white and yellow fibers
areolar and adipose
white fibers
tendons (tight)
yellow fibers
ligaments (loose)
connect muscles to other muscles, to bones or to cartliages
tendons
tendon that connects to itself
aponeurosis
connects bone to cone, cartilage to cartilage, or bone to cartilage
ligaments
- part of the skeletal system
- withstands great pressure, but tears easily
cartilage (chondro)
types of cartilage
- hyaline
- elastic
- fibrocartilage
milky white; forms structures like larynx and trachea; collagen fibers in its intercellular matrix; may “ossify” or harden over time
hyaline
