what are the five functions of connective tissue in the human body? |
support, transport, storage, immune defense, and thermoregulation |
|
|
what is connective tissue? |
connective tissue is made up of a group of specialised cells and tissues |
|
|
the type of connective tissue which includes loose and dense connective tissue in an either regular or irregular conformation |
connective tissue proper |
|
|
the type of connective tissue which includes cartilage, bone, adipose tissue or fat, hemopoietic tissue, blood, and lymph |
specialised connective tissue |
|
|
what is connective tissue proper? |
connective tissue proper includes a variety of cell types and fibres together in a ground substance that makes up an extracellular matrix |
|
|
what is loose connective tissue? |
proper loose connective tissue is usually found under epithelia lining both the body's surface and its internal organ systems, and is usually the first line of defense against infection |
|
|
what is dense connective tissue? |
proper dense connective tissue has many fibres but few cells, this includes tendons, ligaments, submucosa, and reticular layers. These offer support |
|
|
what are the three fibrous elements in connective tissue? |
collagen fibres; these are numerous and offer flexibility and strength |
|
|
what is a tumour of the connective tissue called? |
a tumour of the connective tissue is called a sarcoma |
|
|
which type of cell found in connective tissue secretes immunoglobulin, and is derived from B lymphocytes? |
plasma cells |
|
|
which type of phagocytic cell found in connective tissue is derived from monocytes in the blood? |
macrophages |
|
|
which type of cell found in connective tissue is the principal cell of the immune system? |
lymphocytes |
|
|
which type of cell found in connective tissue responds early to immune challenges and secretes vasoactive and chemotactic substances? |
mast cells |
|
|
which type of cell found in connective tissue stores and releases triglycerides, or fat cells, as needed by the body, and produces hormone and growth factors? |
adipocytes |
|
|
which type of abundant cell found in connective tissue synthesises all fibrous elements and elaborates the matrix? |
fibroblasts |
|
|
which type of phagocytic cell found in connective tissue responds to allergens and parasitic infections? |
eosinophils |
|
|
which type of cell found in connective tissue is capable of contraction and functions similarly to fibroblasts and smooth muscle cells? |
myofibroblasts |
|
|
which type of phagocytic cell found in connective tissue responds to injury and immune challenge? |
neutrophils |
