Tissue Flashcards
Three embryonic tissues called germ layer
Endoderm, mesoderm, ectoderm
Four main types of tissues
Epithelial, muscle, connective, nervous tissues
Two classification of epithelial tissues
Covering and lining, gladular epithelium
Epithilia that consist one layer with the function of absorption, secretion, and filtration
Simple epithelia
Three types of simple epithelia
Simple squamous epithelium, simple cubiodal epithelium, simple columnar epithelium
Have scale like appearance. Ex: endothelium and mesothelium.
Simple squamous epithelium
Have box like cells. Can be found in kidney tubules
Simple cubiodal epithelium
Column like cell which nucleus are elongated and located at the basal end of the cells. These are form in the linig of some sections of the DIGESTIVE SYSTEM and parts of the FEMALE REPRODUCTIVE TRACT
Simple columnar epithelium
Type of epithelium that appears to be stratified
Pseudostratified columnar epithelium
Epithelial cell that consist of several stackes layers
Stratified epithelium
Thus type of epithelium is found in respiratory tract where some of the cells have cillia
Seen in trachea, the cillia moves the mucus produced by the goblet cell
Pseudostratified columnar epithelium q
This functions as protection against physical and chemical wear and tear
Stratified epithelium
The apical cells and basal layer contains either columnar or cubiodal. Most common type of stratified epithelium in the hunan body. The top layer may be covered with DEAD CELLS with KERATIN
Stratified squamous epithelium
Functions as protective tissue. Can be found in sweat glands, salivary gland, mammary gland.
Stratified cubiodal epithelium
Functions for secretions and protection. Can be found in male urethra and some duct glands
Simple columnar epithelium
Can only be found in the urinary system specifically in the bladder, urethra, and the ureters. Kind of stratified epithelium that has gradual CHANGES IN SHAPE of the APICAL CELLS.
Ex: bladder fills with urine
Transitional epithelium
Epithelial tissue that makes up the glands such as THYROID, SWEAT, DIGESTIVE and ADRENAL GLANDS that are responsible for SECRETION of chemical substances
Glandular epithelium
Ductless(no passage) gland that release secretion(hormones) into the surrounding tissues and fluids.
Endocrine glands
Secretion (breast milk, saliva, and sweat) leaves through a duct(passage) that leads to epithelial surface
Exocrine glands
Binds, supports, protect, connect. Can be found in mesoderm. It is dispersed in a matrix.
Connective tissue
Fibroblast
Connective tissue proper
Shock absorption and binding tissue
Loose connective tissue
Fat. Fat storage. Insulation.
Adipose
Weblike. Underlies most epithelia
Areolar tissue
Mesh like supportive framework for soft organs such as LYMPHATIC (white blood cells) TISSUE
Reticular tissue
Contains more collagen for greater resistance to stretching
Dense connective tissue
Parallel fibers. Can be found in ligaments (bone-bone) and tendons (bone to muscle)
Dense regular connective tissue
Random direction of fibers. Can be cound in DERMIS (skin)
Dense irregular connective tissue
Composed of cell adhesion proteins and proteoglycans. A channel for substances to travel between blood capillaries and cells.
Connective tisue fibers and ground substances
Three types of ct fibers + ground substances
Collagen, elastic, reticular
Three specialized ct
Cartilage, bone, blood
Chondrocytes
Cartilage
Embryonic skeleton, ribs, nose, larynx, trachea
Hyaline cartilage
Nasal tip, epiglotis, ear pinna
Elastic cartilage
Knee, jaw joints, intervertebral discs
Fibrocartilage
Hardes connective tissue. Strong and dense.
Bone
Fluid parts of blood
Plasma
Sloid parts of blood
Blood cells
Transports the osygen all ober the body
Rbc or Erythrocytes
Fights harmful microbes
Wbc or Leukocytes
To stop blood clots
Thrombocytes
