If stimulus is strong enough it will spread through whole length of muscle fiber, all of the muscle fibers supplied by a single nerve. In elastic ligaments, dense elastic fiber concentrations convey strong elastic properties while a lesser concentration of collagen serves simply as a mechanical stop to prevent over-stretching under severe stress.
The heart is enclosed in a double-walled sac called the pericardium and is the outermost layer of the heart. Processes — Projections protruding from the bone where muscles, tendons, and ligaments can attach. Arterioles, like arteries, are able to use smooth muscle to control their aperture and regulate blood flow and blood pressure.
All blood vessels contain a hollow area called the lumen through which blood is able to flow.
Ground substance is the background material within which all other connective tissue elements are embedded. The pumping chambers of the heart that support the pulmonary circulation loop are the right atrium and right ventricle.
Allergies are caused in part by inappropriate sensitivity of mast cells. Blood Vessels Blood circulates inside the blood vessels, which form a closed transport system, the so-called vascular system.
Type IIx have low oxidative capacity and fatigue quickly. They either contract maximally or not at all. Mast cells are secretory alarm cells.
The next bundle of muscle fiber is called fascicle. Insulin, Glucagon, and Control of Blood Glucose Glucose is primary energy source during vigorous exercise. In the axilla, the subclavian artery becomes the axillary artery.
Many serious conditions and diseases can cause our cardiovascular system to stop working properly. Veins and Venules Veins are the large return vessels of the body and act as the blood return counterparts of arteries.
Axon — cylendrical projection from the cell body that transmits nervous impulses to other neurons or effector sites muscles, organs. In blood, the ground substance lacks stabilizing macromolecules. One of primary sites for bone growth. The PNS serve two main functions. The ABO blood groups are based on which of two antigens, type A or type B, a person inherits; absence of both antigens results in type O blood, presence of both antigens leads to type AB, and the presence of either A or B antigen yields type A or B blood.
Intervertebral discs are fibrous cartilage that act as shock absorbers and allow the back to move. Greater contractile force and heart rate lead to an increase in blood pressure. Shape, size, and proportion determine their classification. Erythrocytes Erythrocytes, or red blood cells, function primarily to ferry oxygen in blood to all cells of the body.
More than a dozen different varieties of collagen exist in the body, usually identified by Roman numerals. Inner layer immediately surrounding the muscle.
For more on the biochemistry and related pathology of collagen, see Kierszenbaum, Histology and Cell Biology. Monocytes are circulating cells in the blood example at WebPath which can differentiate into macrophages when they enter connective tissue.
In these cells, the metabolic reactions of the mitochondria are uncoupled from ATP synthesis so that energy produced is simply released as heat. Chapter 10 Anatomy of the Muscular System Figure Structure of a muscle organ.A, Note that the connective tissue coverings, the epimysium, perimysium, and endomysium, are continuous with each other and with the tendon.
Note also that muscle. 7 Initial Quiz 1.
Define the terms Anatomy and Physiology. 2. List the levels of organization List the levels of organization of the Human Body from least comof the Human Body from least complex to plex to.
Tissue in the human body: Epithelial: Is made of cells arranged in a continuous sheet with one or more layers, has apical & basal surfaces. A basement membrane is the attachment between the basal surface of the cell & the underlying connective tissue.

fibroblasts from different regions display extensively differentiated patterns of gene expression which may guide differentiated patterns of tissue organization, is the term used in gross anatomy for the connective tissue that loosely binds together various other structures.).
Which connective tissue composes the basement membrane and packages organs, includes a gel-like matrix with all categories of fibers and many cell types?
Areolar Which connective tissue forms the embryonic skeleton and the surfaces of bones at the joints; reinforces the trachea?Tissue study guide for anatomy
