Flashcards in connective tissue: test 1 Deck (35):
what are the general features of connective tissue?
1) Consist of cells surrounded by a matrix
2) Matrix may be fluid, semi-fluid, gelatinous, fibrous, calcified matrix gives the tissue its consistency.
3) Matrix is made by the cells then they live in it.
4) Doesn’t occur on free surfaces (except in joints)
5) Has a nerve supply
6) Has a blood supply
which type of connective tissue cells secrete matrix?
immune cells, engulf pathogens and kill them. which type of connective tissue cells is this ?
immune cells, make antibodies, type of lymphocyte. which type of connective tissue cells is this?
immune cells, creates histamine, and causes swelling, is which type of connective tissue cells?
which type of connective tissue cells are fat storage cells?
various white blood cells of the immune system fight infections, is which type of connective tissue cells?
what is a non-cellular material surrounding the cells gives connective tissue shape and consistency made by fibroblasts made of ground substance?
connective tissue matrix
what is ground substance?
are molecules made of protein and polysaccharides. 4 ground substance molecules are in the matrix.
1. hylauronic acid
2. chondroitin sulfate
3. dermatin sulfate
4. keraton sulfate.
what is hylauronic acid?
viscous and slippery. ex- lubrication in joints, and in the eyeball
what is chondroitin sulfate?
jelly like Ex- in cartilage, bone, and skin.
what is dermatin sulfate?
stronger, tough, not stiff, flexible. Ex- tendons and blood vessels
what is keraton sulfate?
hard and strong. Ex- bone and fingernails
what gives matrix strength, shape or elasticity.
which type of fiber give is tough and strong. Strengthen connective tissue.
which type of fiber forms a mesh to give a tissue shape?
which type of fiber allows tissue to stretch?
which type of connective tissue has fewer fibers so matrix has “space” for cells and ground substances?
Loose connective tissue
what type of connective tissue matrix has all 3 fibers and all 4 ground substance molecules. Acts as a packing material in organs and tissues. Cushions tissue. Ex- subcutaneous layer under skin
Areolar connective tissue
what type of connective tissue fat tissue's Major cell type is adipose cells. Very few fibers. Stores fat. Acts as armor for organs (protect). Fill out spaces?
what type of connective tissue has lots of reticular fibers, Makes internal structure of organs?
Reticular connective tissue
what type of connective tissue has lots of fibers, Room for cells or ground substance?
Dense connective tissue
what type of connective tissue has all fibers run in the same direction. Ex- tendons. Strong in fiber direction, weak perpendicular to fiber direction?
Dense regular connective tissue
what type of connective tissue has lots of fibers ging in all directions. Strong in every direction. Ex- dermis of the skin?
Dense irregular connective tissue
what type of connective tissue has lots of elastic fibers for stretchy tissues? Ex- arteries
Elastic connective tissue
what is stiff, inflexible connective tissue and strong solid matrix with holes (lacuna) for cells (chondrocytes)?
which type of cartilage is the most common cartilage. weakest type? Ex- in joints between some bones, between ribs and sternum, nose.
which type of cartilage contains lots of collagen fibers. Strongest cartilage and the Least flexible? Ex- pubic symphysis, intervertebral discs.
which type of cartilage has lots of elastic fibers. Most flexible cartilage? Ex- pinna of ear (auricle)
what is oseus tissue?
what is the term for: an epithelial tissue over a connective tissue?
what is a mucous membrane?
lining open cavity
has single cell glands to secrete liquid to keep membrane moist.
what is serous membrane?
epithelial membrane lining a closed cavity has 2 layers:
1. parietal layer
2. visceral layer
between the layers is serous fluid.
which layer of the serous membrane lines the cavity?
