Tissues Flashcards
Tissue for protection, secretion, absorption, excretion:
Lack blood vessels, readily divide; cells are tightly packed.
Epithelial
Tissue that binds, supports, protects, fills spaces, store fat, produces blood cells:
Most have good blood supply; cells are farther apart than epithelial cells.
Connective
Tissue for movement:
Able to contract in response to specific stimuli.
Muscle
Tissue that transmit impulses for coordination, regulation, integration, and sensory reception:
Cells communicate with each other and with other body parts.
Nervous
Describe structure/shape of simple squamous epithelium tissue
It is one layer of flattened, thin cells
Describe the structure of simple columnar epithelium tissue
One layer of elongated cells (longer than they are wide)
Describe the structure of simple cuboidal epithelium tissue
One layer of cube like cells. They have a centrally located nuclei
Describe structure and shape of pseudostratified columnar epithelium
It is really just a single layer of cells, but appears to be stratified because of different sizes of the cells and different location of their nuclei
What is transitional epithelium?
Tissue that changes shape and size in response to increased tension
Where do you find simple squamous epithelium?
You find it in the air sacs, covering cavity membranes and lining inside of blood and lymphatic vessels
Where do you find simple columnar epithelium?
Nonciliated simple columnar epithelium lines uterus, most organs of digestive tract.
Where do you find simple cuboidal epithelium?
Covering ovaries, lines most kidney tubules and ducts of certain glands
Where do you find stratified columnar epithelium?
Male urethra and parts of the pahrynx
Where do you find stratified cuboidal epithelium?
Lines larger ducts of mammary glands (brystkirtler), sweat glands, salivary glands and pancreas
Where do find stratified squamous epithelium?
Epidermis (outer layer of skin)
Where do you find pseudo stratified columnar epithelium?
Lining passages of respiratory passages
Where do you find transitional epithelium?
Ureters (urinledere) and urinary bladder
What is stratified in relation to tissue?
When there’re more than just one layer of cells
What is a cartilage cell called?
Chondrocyte
What are the pockets in which cartilage cells are in
Lacuna
What is the center of a cuboidal epithelium and stratified cuboidal epithelium
Lumen
Where are goblet cells located
Simple columnar epithelium and pseudo stratified columnar epithelium
Glands that release fluid by exocytosis
Merocrine gland
Glands that lose small portions of their glandular cell bodies
Apocrine glands
Glands that release entire cells that disintegrate to release cell secretions
Holocrine cells
Glandular fluid that is typically watery, and has a high concentration of enzymes
Serous fluid
Thicker glandular fluid that is rich in the glycoprotein mucin and abundantly secreted by cells
Mucus
What is the central part of a bone cell
Central canal
What is a bone cell
Osteocytes
What are the layers of the extra cellular matrix of an osteon
Lamella
Circular formations in the bone tissue
Osteon
Connections for materials in the blood cells
Canaliculi
Bonds skin to underlying organs and fills spaces between muscles
Areolar Tissue
Supports walls of liver and spleen
Reticular
Binds organs:
Tendons, ligaments, deeper layers of skin.
Dense connective tissue
Supports, protects, provides framework:
Nose, ends of bones, rings in the walls of respiratory passages
Hyaline
Supports, protects, provides flexible framework:
Framework of external ear and parts of larynx
Elastic cartilage
Supports, protects, absorbs shock:
Between bony parts of spinal column, parts of pelvic girdle and knee
Fibrocartilage
Line body cavities that lack opening to the outside
Serous membrane
Line cavities that open to the outside of the body
Mucous membrane
Skin
Cutaneous membrane
Lines joints, made completely of connective tissues
Synovial
