Psysiology chapter 4

The ribosomes synthesize proteins while attached to the ER, resulting in transfer of their newly synthesized proteins into the lumen of the RER where they undergo modifications such as folding or addition of sugars. The function of aquaporins is to allow the movement of water across the lipid-rich, hydrophobic cell membrane Figure 5.

Microtubules are the thickest of the cytoskeletal fibers. Lysosomes also use their hydrolytic enzymes to destroy disease-causing organisms that might enter the cell.

Under conditions of stress, sympathetic nervous activity increases, resulting in the direct vasoconstriction of afferent arterioles norepinephrine effect as well as stimulation of the adrenal medulla. This edition updates many other anatomical terms and deletes most eponyms in keeping with the Terminologia Anatomica.

Antiduretic hormone ADH promotes the recovery of water, decreases urine volume, and maintains plasma osmolarity and blood pressure. Some topics Saladin addresses include: Strong evidence points to endosymbiosis as the explanation.

Additionally, enzymes within plant vacuoles can break down macromolecules. Presentation package plus image bank. Includes the study of cells, tissues, and the integumentary, skeletal, muscular and nervous systems. The functional units of nerve tissuePossess a cell body and one or more neuron processRespond to environmental changes by making neural impulses Intermediate filaments are of intermediate diameter and have structural functions, such as maintaining the shape of the cell and anchoring organelles.

It enzymatically converts angiotensinogen made by the liver, freely circulating into angiotensin I. Several vesicles can be seen near the Golgi apparatus. When tissue factor binds with another factor in the extracellular matrix, it causes platelets to adhere to the wall of the damaged blood vessel, stimulates adjacent smooth muscle cells in the blood vessel to contract thus constricting the blood vesseland initiates a series of steps that stimulate the platelets to produce clotting factors.

Keratin, the compound that strengthens hair and nails, forms one type of intermediate filament. It is produced in the lungs but binds to the surfaces of endothelial cells in the afferent arterioles and glomerulus.

What structures does an animal cell have that a plant cell does not have. The extracellular matrix consists of a network of substances secreted by cells. Cardiac electrophysiology is the science of elucidating, diagnosing, and treating the electrical activities of the heart.

The term is usually used to describe studies of such phenomena by invasive (intracardiac) catheter recording of spontaneous activity as well as of cardiac responses to programmed electrical stimulation (PES).

the kidney is referred to as an excretory organ because it excretes __1__ wastes. it is also a major homeostatic organ because it maintains the electrolyte, __2__ and __3__ balance of the blood. The Anatomy and Physiology of Personality.
