Parathyroid Nervous System Research Paper

526 Words3 Pages

3. The calcium levels in the blood and bones are being controlled and regulated by the parathyroid glands. Parathyroid glands are next to and sometimes inside the thyroid glands. Parathyroid glands are small glands in the endocrine system that control how much calcium is inside our bones, which affects how much calcium is in our blood. Calcium control is important because it lets the normal conduction of electric currents to run in our nerves and is also, the main element that causes our muscles to contract. The muscles contract when the brain signals and the body will pull calcium from the blood into the muscle cells. The calcium will then bind with the troponin, a complex of three regulatory proteins important to muscle contraction, which then draws it …show more content…

When the calcium disappears, the troponin and tropomyosin return to position, the myosin and actin detach, and the filaments glide apart to loosen the muscle. Going back to the parathyroid glands, there are four glands and have very rich blood supply. Rich blood supply is good since they are obliged to observe the calcium level in the blood 24 hours a day. When the parathyroid glands have blood filtering, they expose the amount of calcium existing in the blood and behave by producing more or less parathyroid hormone (PTH). PTH is released to regulate calcium levels in a body. When the calcium level in the blood is scarce, the cells of the parathyroids sense this and produce additional parathyroid hormone. When the parathyroid hormone is freed into the blood, it flows to act in a number of places in order to enlarge the amount of calcium in the blood. When the calcium level in the blood is too excessive, the cells of the parathyroids produce less parathyroid hormone or stop completely, which allows the calcium levels to

As muscle contractions occur they myosin filaments bind and attach to the actin filaments Myofibril is the contractile threads found in striated muscle cells and a segment of myofibril is called a sarcomere. The role of the sarcoplasmic reticulum is storing calcium ions, as well as releasing calcium ions during muscle contractions and reabsorbing calcium ions when the muscles relax. Actin is a protein that forms the thin filament in muscle cells. Thin filaments are made up of two long chains of actin molecules that are twisted around one another.

The primary function of calcium is it used for 99% of growth, development, and maintenance of bones and teeth that provide support of the skeletal structure. Calcium also plays a role in cell signaling, blood clotting, muscle contractions and nerve function. The recommended DRI for this mineral for me is 1,000mg (not exceeding 2,500mg) and my weekly intake average for calcium was 684.2. Due to my low intake of this mineral it puts me at risk for osteoporosis if I continue consume inadequate amounts. Osteoporosis is a disease that causes the bones to become very weak, making the bones more prone to fractures.

Neurons transmit information to each other and to muscles, organs and glands. The nerve impulse is sent from the axon of one neuron to the dendrite of another neuron. The neuromuscular junction as labeled in Part A of this assignment, shows that there is a space between the axon of a neuron and the motor plate of the muscle cell. The two parts do not actually touch each other. When the football player’s brain sends a message to move during the game, the nerve impulse is sent from neuron to muscle cell.

Rhabdomyolysis Research Paper

So what exactly is rhabdomyolysis? It is an imbalance in the muscle that happens when the muscle tissue of an affected area breaks down quickly, which can release its toxins into your blood stream. This can be caused by a hard hit to a muscle, causing muscle injury, as well as from the use of certain narcotics and even severe dehydration (Cervellin 2010). As learned in the course muscles are composed of sarcolemma which is the membrane that is composed of many Na+, K+ and Na+, CA+ channels that when a muscle is injured , stop functioning

An unbalance in these hormones would cause changes in the function and structure of the gland. In the setting where there isn’t a sufficient amount of Thyroxin synthesized by the gland, there is an increase in TSH production. Over production of TSH causes hyperplasia of the gland just to match normal thyroid levels. This would then cause a goiter to form. When the goiter is grown significantly, pressure is put on the esophagus and trachea, causing respiratory

Anti-diuretic hormone is connected to release of water retention and blood dilution as a result of low sodium levels.

This hormone is released by the pituitary gland and acts on the thyroid gland controlling the release of hormones by the thyroid. If someone has low thyroid levels they can experience low energy levels and depression. These are two symptoms experienced by Eric between the ages of 11 and 15. Eric became sluggish at little league and introverted showing signs of depression. The thyroid also regulates the amount of calcium in the blood and bones via Calcitonin.

Hypoparathyroidism Research Paper

Hypoparathyroidism is not only a disorder, but a cure for another calcification deficiency, Basal Ganglia. The Basal Ganglia is grey matter near the base of the cerebral hemispheres, consisting of the corpus striatum (Macpherson 61). There are a lot of people who are being treated for basal ganglia today with hypoparathyroidism. The reason why hypoparathyroidism is a cure for basal ganglia is because it shows up in the hormones that are located in the brain. The basal ganglia makes it possible for a person to release a great amount of insulin throughout the brain area and into the rest of the body.

Melatonin aids in sleep as well as ones biological clock. The thymus is located between the lungs behind the sternum and produces thymosin which help with immunity. The thyroid gland is located under the larynx in the neck and secretes calcitonin which is a hormone that decreases blood calcium levels which targets bones. The parathyroid gland is attached to the thyroid lobe (sits on the thyroid gland) and secretes PTH which is a hormone that does the opposite of calcitonin and increases blood calcium levels which target bone, kidneys, and the intestines. The adrenal glands are located on top of the kidney and consist of the adrenal cortex and the adrenal medulla.

Every muscle receives nerve supply from nerves that split into smaller nerve fibers. These spread along the muscle, where a tiny gap called neuromuscular junction (NMJ) is found between the end of each nerve fiber and the muscle surface. As the brain sends messages to the muscles through the nerves, a chemical (neurotransmitter) called acetylcholine is released into the NMJ. The acetylcholine molecules

Essay On Muscle Contraction

1506 Words | 7 Pages

There are four steps in the muscle contraction cycle. At the beginning of contraction, the sarcoplasmic reticulum releases ca2+ into the sarcoplasm where they will bind to troponin. Troponin then moves tropomyosin away from the myosin binding sites on actin. Once binding sites are free the contraction cycle will begin. Step one of the contraction cycle is ATP Hydrolysis.
