Tissues Flashcards
The most common type of cartilage found in the body, it is composed of closely packed collagen fibers that make it tough but more flexible than bone ( found at the ends of bones and In joints)
Hyaline cartilage
Contains a plethora of electric fibers which form dense, branching bundles that appear black microscopically. (Found in the pinnae of animals)
Elastic cartilage
Contains thick bundles of collagen fibers, but has fewer chondrocytes. (Found in the spaces between vertebrae of the spine, between bones in the pelvic girdle and the knee joint)
Fibrocartilage
Glands that do not have ducts or tubules and whose secretions are distributed throughout the body
Endocrine glands
Posses ducts that discharge secretions directly into nearby areas where they may cover cell surfaces or empty into body cavities
Exocrine glands
The ductless goblet cell
Unicellular glands
The entire secretory cell is destroyed in the act of releasing its secretory product
Holocrine glands
Are watery and contain high concentration of enzymes
Serous secretions
Involves the loss of the top part of the cell, called the apex of the secretory cell (can be found in mammary tissue)
Apocrine glands
The secretory cells remain intact during the secretory process ( pancreas, sweat glands, and salivary glands)
Merocrine glands
A mucus produced by glands to reduce friction between organs and assist with the passage of food and waste
Mucin
Specialized protein molecules that are produced in through the rough endoplasmic reticulum, packaged into granules by the golgi and discharged from the cell.
Secretions
A layer of mucus which are disease fighting molecules that help to protect animals from pathogens
Immunoglobulins
Bacteria and viruses
Pathogens
Found everywhere in the body and Is the most abundant tissue by weight. Provides support, insulation, and plays a role in the healing process. ( blood, tendons, fat, cartilage, bone)
Connective tissue
