|
|
|
Chondroblast/chondrocyte |
In cartilage (supportive) |
|
|
|
Osteoblasts/osteocyte |
Makes bone (supportive) |
|
|
|
Hemocytoblast |
In blood (fluid) |
|
|
|
Blast |
Actively mitotic cell, secreting matrix, young |
|
|
|
Cyte |
Mature cell in the matrix that nourishes nearby matrix |
|
|
|
Cells are ________ in a matrix. Lots of ________ material, _________ and ground __________. |
Dispersed. Extra cellular. Fibers. Substance. |
|
|
|
Ground substance |
Large part of matrix, criss crossed protein, fibers, fluid or mineralized as in bone. It is what the cells float in |
|
|
|
Ground substance comes from |
Mesodermal layer |
|
|
|
3 classifications |
Connective tissue proper (loose vs dense) Supportive (cartilage and bone) Fluid (flows all around) |
|
|
|
Fibroblast |
Most abundant cell in connective tissue proper, produce protiens and polysaccharides which become ground substance |
|
|
|
Adipocytes |
Store lipids or surplus energy |
|
|
|
Menechemal cell |
Multipotent adult stem cell, can be any type of connective tissue. |
|
|
|
Collagen fiber |
Great tensile strength, resist stretch, found in ligaments and tendons, made from fibrous protein subunits, appear white (Bones and ligaments) |
|
|
|
Elastic fibers |
Long and thin, returns to original shape after stretch, made from protein elastin, appear yellow (Skin, blood vessels and lungs) |
|
|
|
Reticular fiber |
Made of same protein as collagen, remain narrow and arrayed in branching network, found throughout the body but most around soft organs. Framework for spleen, lymph nodes and bone marrow. |
|
|
|
Adipose tissue |
Fat storage cells, large number of papillaries |
Loose connective tissue |
|
|
Areolar tissue |
Little specialization, found in weblike pattern |
Loose connective tissue |
|
|
Reticular tissue |
Mesh like supportive framework especially for organs |
Loose connective tissue |
|
|
Dense connective tissue |
More collagen fibers than loose, greater resistance to stretching |
|
|
|
Regular connective tissue |
Fibers run parallel for greater strength Ligaments and tendons |
Dense connective tissue |
|
|
Irregular connective tissue |
Fibers run in all directions Skin |
Dense connective tissue |
|
|
Supportive connective tissue |
Hyaline cartilage Fibrocartilage Elastic cartilage Bone |
|
|
|
Cartilage |
Avascular and bound to ground substance |
|
|
|
Hyaline cartilage |
Most common Short dispersed collagen fibers Strong and flexible Joints, nose, end plates of bone, trachea |
|
|
|
Fibrocartilage |
Thick bundles of collagen fibers that are better at absorbing shock Knee, jaw, intervertebral disks |
|
|
|
Elastic cartilage |
Elastic fibers as well as collagen Ear lobes |
|
|
|
Bone |
Rigid extra cellular matrix, collagen in a mineralized ground substance of calcium phosphate, highly vascular, cancellous bone is spongier than compact bone |
|
|
|
Fluid connective tissue |
Blood and lymph |
|
|
|
Blood |
Formed elements come from stem cells in the bone marrow, transport rbc, wbc, platelets and wastes 50% water |
|
|
|
Lymph |
Transport WBC, excess fluid and fats |
|
|
|
Types of membranes |
Synovial membrane Cutaneous membrane Mucous membranes Serous membranes |
|
|
|
Synovial membrane |
Dense irregular tissue Aeolar tissue Lines the cavity of moveable joints Produces synovial fluid for lubrication |
|
|
|
Cutaneous membrane |
Stratified squamous keratinized epithelium Areolar tissue Dense irregular tissue Skin covering body |
|
|
|
Mucous membrane |
Line body cavity and internal passageways Digestive, respiratory, reproductive, excretory tracts |
|
|
|
Serous membranes |
Line cavities that don’t open to the outside Covers organs in those cavities Produces a fluid for lubrication Pleura, pericardium, peritoneum |
|
|
|
Types of glands |
Exocrine Endocrine Merocrine Apocrine Holocrine |
|
|
|
Exocrine |
Secrets through a duct |
|
|
|
Endocrine |
No duct |
|
|
|
Merocrine |
Sweat glands all over the body that are active at birth |
|
|
|
Apocrine |
Active at puberty Found in axilla and pubic region Secretes organic material that degrades and causes body odor |
|
|
|
Holocrine |
Produces oils after puberty Not found in thick skin |
|
