Anatomy 4 Boyyyy Flashcards
Epithelium
Is the lining, covered, and glandular tissue of the body
Functions of epithelium
Protection, absorption, filtration, secretions
Characteristics of epithelial
Fit tightly together, have no blood supply, regenerate easily, 1 unattached surface
Epithelial simple
One layer, absorb, filter, secrete
Epithelial stratified
Multi-layered, for protection
Epithelial squamous
Flat cells
Epithelial columnar
Vertical, rectangular shaped cells
Epithelial cuboidal
Square shaped cells
Transitional epithelial
Transforms from one shape of cell to another
Endocrine glands
Ductless, secretions diffuse into bloodstream
Exocrine glands
Have divots that lead to surface to release secretions
Connective tissues
Connects body parts
Functions of connective tissue
Protecting, supporting, and binding together other body tissues
Connective tissue characteristics
Usually good blood supply, extra cellular matrix
Types of connective tissue
Blood, bone, hyaline cartilage, dense fibrous tissues, areolar tissue, adipose tissue, reticular connective tissue
Blood
The only fluid tissue of the body
Nervous tissue
Irritability and conductivity- receive and conduct electrical impulses from one part of the body to another
Muscle tissue
Specialized to contract or shorten to produce a movement
Skeletal muscle
Voluntary control (looks stringy)
Cardiac muscle
Found in the heart- involuntary control
Smooth muscle
Found in the walls of hollow organs:( stomach, bladder, uterus, blood vessels, esophagus
Peristalsis
A wavelike motion that keeps food moving through the esophagus and small intestines
Cutaneous membrane
Lines all body cavities that open to the exterior- epithelial
Serous membrane
Line all body cavities that are closed to exterior-epithelial
Peritoneum
Lines abdominal cavity and covers its organs
Pleura
Lines the lungs
Pericardium
Surrounds the heart
Synovial membrane
Surround joints providing a smooth surface and secrete lubricating fluids-connective
Tissues
Groups of cells that are similar in structure and function
