Tissues of the Body
Tissues
By: Alexis Ortiz-Robles
Muscle Tissue
Skeletal Tissue
Skeletal Tissue
Functions
- Move and stabilizes skeleton
- Guard entrances and exists to digestive, respiratory, urinary tracts
- Generates heat
- Protect internal organs
Functions
Location
- Found in skeletal muscle
- Looks like a elongated, cylindrical, banded cells with multiple nuclei
Location
Cardiac Muscle Tissue
Cardiac Tissue
Function
- To move blood and maintain blood pressure
Function
Location
- Found in the heart
- Looks like short, branched, usually with single nucleus cells
Location
Smooth Muscle Tissue
Smooth Tissue
Function
- Move food, urine, reproductive sections
- Control diameter of respiratory passageways and blood vessels
Function
Location
- Found throughout the body (skin, blood vessel walls, many organs of various systems)
- Look like short, spindle-shaped, non-striated, have a single nucleus cells
Location
Nervous Tissue
Nervous Tissue
Neurons
Function
- Transfer information around the body and perform information processing
Function
Location
- Found throughout the whole body
- Looks like a long tube with branches on each end
Location
Neuroglia
Function
- Maintain physical structure of nervous tissue
- Repair nervous tissue framework after injury
- Perform phagocytosis
- Provide nutrients to neurons
- Regulate the composition of the interstitial fluid surrounding neurons
Location
- Found in central nervous system and Peripheral nervous system
- Looks like a cell holding two other cells together
Location
Epithelial Tissue
Epithelial Tissue
Squamous Epithelium
Simple
- Most delicate epithelium
- Functions include: absorption, diffusion, and reduction of friction
- Found in protected regions such as peritoneum, capillary wall, inside eye, or lung aveoli
Simple
Stratified
- Located where severe mechanical or chemical stresses exit
- Many layers of cells
- Superficial layer flattened
- Forms surface of skin and lines mouth, throat, esophagus, rectum, anus, vagina
Stratified
Cuboidal Epithelium
Simple
- Functions in secretion and absorption,
- Lines exocrine glands and ducts
- Lines parts of kidney tubules and thyroid gland
Simple
Stratified
- Rare tissue type
- Found in ducts of sweat glands and mammary glands
Stratified
Columnar Epithelium
Simple
- Found where absorption or secretion takes place
- Line stomach, intestine, gallbladder, uterine tubes, kidney ducts
- May have microvilli or cilia on apical surface
Simple
Stratified
- Rare tissue type
- two or more layers of cells
- Found lining large ducts such as those of salivary glands or pancreas
Stratified
Transitional Epithelium
Transitional Epithelium
Function
- Unusual stratified epithelium that can stretch and recoil without damage
Function
Location
- Found only in urinary system
- Can change appearance
Location
Connective Tissue
Proper Tissue
Loose
Areolar Tissue
- Most common connective tissue proper
- Packing material of the body
- Has all connective tissue proper cell types
Areolar Tissue
Adipose Tissue
- Found deep to skin in various areas of the body
- Forms layer of padding around eyes and kidneys
- Cells account for most of tissue volume
Adipose Tissue
Recticular Tissue
- Found in liver, kidney, spleen, lymph nodes, and bone marrow
- Provides support and resists distortion
- Many reticular fibers forming network
Recticular Tissue
Dense
Regular
- Most volume occupied by extracellular fibers
- Found in cords (tendons, ligaments) or sheets
- Collagen arranged in parallel bundles
Regular
Irregular
- Fibers arranged in meshwork (no consistent pattern) to resist tension in many directions
- Found covering visceral organs; in superficial layers of bones, cartilages, and peripheral nerves, in dermis of skin
Irregular
Elastic
- More elastic fibers than collagen
- Is springy and resilient
- Found between vertebrae, in walls of large blood vessels, erectile tissues of penis
Elastic
Fluid Tissue
Fluid Tissue
Blood
- Watery matrix called plasma
- Contains red bloods cells, white blood cells, and platelets
Blood
Lymph
- Watery matrix called lymph located in lymphatic vessels
- Collected from interstitial fluid
- Majority of cells are lymphocytes
Lymph
Structural Tissue
Cartilage
Cartilage
Hyaline Cartilage
Hyaline Cartilage
Function
- Provides stiff but flexible support
- Reduces Friction
Function
Location
- Found between ribs and sterum, covering bones in mobile joint, part of nasal septum, supporting respiratory passageways.
- Has the shape of a butterfly
Location
Elastic Cartilage
Elastic Cartilage
Function
- Distorts without damage and returns to original shape
Function
Location
- Found in external ear and smaller internal structures
- Looks like a tadpole
Location
Fibrocartilage
Function
- Durable and tough
- Resists compression, prevents bone to bone contact, and limits relative movement
Function
Location
- Found in knee joint, between pubic bones, and in internal discs
- Looks like donuts stacked on eachother
Location
Bone
Function
- Connective tissue with solid, crystalline matrix
- Small volume of ground substance
- 2/3 of matrix is calcium salts (provide strength)
Function
Location
- Found within bones
