Where in the body can you find Hyaline Cartilage?
It is a primary support cartilage found many placesIt. It is for the articular cartilage of the joint, nose, throat, Attaches ribs to sternum
List the three types of cartilage from most supportive to most malleable
Hyaline Cartilage, Fibrocartilage Elastic Cartilage
Where in the body can you find elastic cartilage?
Ear, Epiglotis
Where in the body can you find Fibrocartilage?
Intervertebral discs, meniscus, pubic symthesis
What is happening in tissue in Lupus and what are common symptoms?
Inflammation of the connective tissue caused by autoimmune disease. Common symptoms joints, loss of hair, ulcers, can cause kidney failure from accumulation of antigens.
Where can you Adherens Junctions
Common many locations where you don’t need extremely strong adherence for structural stability such as liver and pancreas
What are the components of the Adherens junctions
Microfilaments in the cytosol and Plaques formed transmembrane glycoproteins
What are structures of desmosomes?
Intermediate filaments that attache throughout the cell, plaques made from glycoproteins that are cross linked and fused together
Where are desmosomes found?
In cardiac muscle, skin
List types of cell junction strongest to weakest
Desmosomes, Adherens Junctions, Tight Junctions
What type of cell junction attaches epithelial sells to the basement membrane?
Hemidesmisomes
What type of Connective tissue is the basement membrane made of
Reticular fibers
What is the function and structure of Gap Junctions
Facilitate communication between two cells through protein channels called connexions
Where are common places to find gap junctions
Heart, Smooth muscle
What kind of glands secrete their product directly into the blood stream and what products do the secrete?
Endocrine glands which secrete hormones
Name three types of Exocrine gland
Simple, Acinar, Tubuloacinar
Describe the secretion method and location in the body of simple exocrine glands
Simple glands secrete from an unbranched duct. They are found in the both types of sweat glands ( the eccrine and apocrine).
Describe the secretion method and common location in the body of acinar exocrine glands
Acinar glands secret from a secretory sac. They are found in the mammary cells
Describe the secretion method and location in the body of tubuloacinar exocrine glands
Tubuloacinar glands secret from both their face and the tube of the duct, often secreting different things from the different locations. The are found in the pancreas where tubular component produces bicarbonate and acinar component produces digestive enzymes
What is Sjogren’s Syndrome
an autoimmune disease causing dry mouth and eyes due to gland inflammation
What are the methods of glandular secretions
Merocrine, Aporcrine, Holocrine
What is the most common type of glandular secretion
Merocrine
What is Holocrine secretion and where in the body can is be found?
The entire cell explodes upon producing a certain amount of material. Usually oily such as sebaceous glands,
What is the only unicellular gland and what does it produce?
Gobblet Cells produce mucus
