Connective Tissue
Muscle Tissue
Fibrocartilage
Cardiac Muscle
Skeletal Muscle
Elastic Cartilage
Bone
- Connective Tissue
- Found in betwwen discs in vetabre and knee joints as well as in pubic symphysis
- Used as cushion
- Highly compressable
- Muscle Tissue
- Attached to connective tissue
- Provide voluntary control of muscles
- Has striations (no intercalated discs)
- Muscle Tissue
- Found in and around the heart
- Helps the heart pump blood (involuntary)
- Has striations and intercalated discs.
- Connective Tissue
- Found at the exterior of your ear and the epiglottis
- Provides elasticity
- Usually take more of the stain/color. can see the messy fibers in between cells
Reticular
Smooth Muscle
- Connective Tissue
- Found in bone
- Used to protect and support body
- Made of Calcium, salts, and large amounts of collagen fibers
- Connective Tissue
- Found in lymph nodes, spleen, and bone marrow
- Interwoven fibers that support lots of cells
- Paste-like substance
- Muscle Tissue
- Found surrounding hollow organs
- Involuntary function (surrounding hollow organs)
- No striations
Blood
- Connective Tissue
- Found all throughout the body
- Functions as transport vehicle for materials
- White blood cells pick up more stain.
Hyaline Cartilage
- Connective Tissue
- Found at the edge of long bones, ribs, trachea and nose.
- Keeps bones from rubbing together.
- Glassy-like,rubbery; most common cartilage
Adipose
Dense Fibrous Connective Tissue
- Connective Tissue
- Found around around organs and under the skin
- Cushions and insulates vital organs as well as stores fat that serves as a source of energy.
- Loose connective tissue composed of adipocytes
Areolar
- Connective Tissue
- Found in tendons and ligaments
- Tendons: attatch muscle to bone
- Ligaments: attatch bone to bone
- Contains LOTS of collagen fibers
- Connective Tissue
- Usually found under epithelial tissue
- Holds organs in place and attaches epithelial tissue to other underlying tissues
- It is soft and pliable
Four Types of Tissue
Nervous Tissue
Motor Nerve Unit
Nerve Cell (neuron)
- Nerve Tissue
- Located in the CNS
- Helps to trigger muscle movement.
- Stacked muscles with an axon going through it
Epithelial Tissue
- Nerve Tissue
- Found in the brain, spinal cord, and and nerves
- Sends and receives impulses from other areas of the body
- Cell body is the head and axon is the tail
- Epithelial
- Connective
- Nervous
- Muscle
Simple Columnar (Ilium)
Simple Cuboidal (Kidney)
Psuedostratified Columnar (Trachea)
- Epithelial Tissue
- Found in Digestive Tract
- Allows absorption and secretion
- Single-layer of tall cells (no cilia)
- Epithelial Tissue
- Found in Kidney (around tubules) and the ducts of glands
- Allows secretion and absorption
- Single-layer of cube like cells.
- Epithelial Tissue
- Found in sperm and carrying ducts
- Allows secretion and propulsion of Mucous
- Tall cells with cilia
Transitional Epithelium (Bladder)
Simple Squamous (Lungs)
Stratified Squamous (Skin)
- Epithelial Tissue
- Found in bladder
- It's only function is to stretch to allow room
- It's a combination of different types of cells and it is more than one layer
- Epithelial Tissue
- Found in the lining of body cavities and lining of the lungs
- Usually forms a membrane that allows diffusion and filtration
- single-layer of flat cells
- Epithelial Tissue
- Found in skin, mouth , and esophagus
- Protection of underlying areas where friction i common
- Many layers of flat cells
