-
4 types of tissue
Epithelial, connective, muscle, & neural
-
Simply squamous epithelium locations
- Lines sacs of lungs
- walls of capillaries
- blood vessels
- heart & body cavities
-
Simple cuboidal epithelium locations
- Kidney tubules
- ducts of glands
-
Pseudostratified columnar epithelium locations
Lines upper respiratory tract
-
Keratinized stratified squamous epithelium locations
- Palms of hands
- soles of feet
-
Stratified squamous epithelium locations
- Forms outer layer of skin
- lines oral cavity, vagina & rectum
-
Simple columnar epithelium locations
Lining intestines & uterus
-
Transitional epithelium locations
Ureters & urinary bladder
-
Collagen Fiber
- Strong flexible,but not elastic
- white fibers that stain pink or blue
-
Elastic Fiber
- Stretchy- elastin
- yellow fiber that stain purple
-
Reticular Fiber
- Resist force, stabilizes
- spongy organs (ex.spleen, lymph nodes)
-
Ground Substance
- Fills space outside of the cell
- supports cells and fibers
-
Adipose connective tissue
- Functions: Insulates, cushions & stores energy
- Cells: Adipocytes
- Locations: Beneath skin, fills space between muscles
-
Dense regular connective tissue
- Tightly packed collagen fibers
- Functions: Attachment
- Cell: Fibroblast
- Location: Tendons, & ligaments
-
Elastic connective tissue
- Elastic fibers with wavy arrangement
- Functions: Expansion & contraction of organs
- Cell: Fibroblast
- Location: Walls of hollow organs, (Ex. stomach, intestines, esophagus, bladder)
-
Reticular connective tissue
- Functions: Supportive framework for spongy organs
- Cell: Fibroblast
- Location: Liver, spleen, kidneys
-
Areolar connective tissue
- Functions: Anchors skin to underlying tissues
- Cell: Fibroblast
- Location: Underlines epithelial tissue and skin
-
Chondrocytes
Cartilage cells
-
Lacunae
Small chambers that house chondrocytes
-
Perichondrium
- Covers cartilage with fibrous connective tissue
- Receives nutrients & oxygen by diffusion
