Difference Between Anatomy And Physiology

By Dr. Joseph H Volker | 2018-08-30T11:03:29+00:00 August 8th, 2018|General, Physiology|0 Comments

Difference between Anatomy and Physiology is this that Anatomy is the study of structure while on the other hand Physiology is the study of Functions. Anatomy is the study of structure: Anatomy, which suggests "a cutting open" is the study of internal and external structures of the body and the physical relationships amongst body parts [...]

DNA Replication

By Dr. Joseph H Volker | 2018-08-30T09:23:49+00:00 August 8th, 2018|General, Physiology|0 Comments

The law of complementary base pairing shows that we can forecast the base series of one DNA strand if we understand the series of the other. More notably, it allows a cell to reproduce one strand based upon info in the other. The essential actions of the replication process are as follows : The double [...]

Major Skeletal Muscles

By Dr. Joseph H Volker | 2018-08-30T10:55:38+00:00 August 8th, 2018|Muscular System, Physiology|0 Comments

There are more than 600 muscles in the body, but only a few of the major muscles are considered here. Muscles of Facial Expression And Mastication Muscles of the face and scalp produce the facial expressions that help communicate feelings, such as anger, sadness, happiness, fear, disgust, pain, and surprise. Most have origins on skull [...]

Small Intestinal Motility

By Dr. Joseph H Volker | 2018-08-30T08:55:11+00:00 August 8th, 2018|Gastrointestinal System, Nervous system, Physiology|0 Comments

The small intestine is divided into duodenum, jejunum, and ileum, with the duodenum and jejunum being the major site of digestion and absorption. Chyme takes 2 to 4 hours to move through the 5 m of the small intestine. Segmentation, which mixes intestinal contents and enhances contact of the chyme with the intestinal microvilli, is [...]

Disorders of The Respiratory System

By Dr. Joseph H Volker | 2018-08-30T09:47:26+00:00 August 8th, 2018|Physiology, Respiratory System|0 Comments

Inflammatory Disorders Chronic obstructive pulmonary disease (COPD) is a group of disorders in which there is a long-term obstruction that reduces airflow to and from the lungs. The two most important COPDs are chronic bronchitis and emphysema. Bronchitis is inflammation of the bronchi, and it is characterized by excessive mucus production that partially obstructs air [...]

Lactation – The Control of Lactation and Milk Ejection

By Dr. Joseph H Volker | 2018-08-30T10:54:31+00:00 August 8th, 2018|Endocrine System, Physiology, Reproductive System|0 Comments

High blood levels of estrogens and progesterone during pregnancy stimulate the development of the mammary glands and enlargement of the breasts in preparation for milk secretion, or lactation (lak-ta'-shun). Although the mammary glands are capable of secreting milk, the high levels of estrogens and progesterone inhibit the hypothalamus so that milk secretion does not occur [...]

Peroxisomes and Its Functions

By Dr. Joseph H Volker | 2018-08-30T08:39:34+00:00 August 8th, 2018|General, Physiology|0 Comments

Peroxisomes or microbodies are the membrane minimal vesicles like the lysosomes. Unlike lysosomes, peroxisomes are pinched off from endoplasmic reticulum and not from the Golgi apparatus Peroxisomes consist of some oxidative enzymes such as catalase, urate oxidase and D-amino acid oxidase.   Oxidative enzymes, as the name suggests, utilize oxygen (02), in this case to [...]

Dense Connective Tissue

By Dr. Joseph H Volker | 2018-08-30T09:41:44+00:00 August 8th, 2018|General, Physiology|0 Comments

Like loose connective tissues, dense connective tissues help binding tissues together and offering assistance fororgans Nevertheless, dense connective tissue has far less cells and ground substance and more various, thicker, and "denser" protein fibers. These tissues likewise include far less blood vessels than loose connective tissues There are 3 types of dense connective tissue: dense [...]

Disorders of The Nervous System – Inflammatory and Non Inflammatory

By Dr. Joseph H Volker | 2018-08-30T11:12:15+00:00 August 8th, 2018|Nervous system, Physiology|0 Comments

Inflammatory Disorders Meningitis (men-in-ji '-tis) results from a bacterial, fungal, or viral infection of the meninges. Bacterial meningitis cases are the most serious, with about 20% being fatal. If the brain is also involved, the disease is called encephalitis. Some viruses causing encephalitis are transmitted by bites of certain mosquitoes. Neuritis is the inflammation of [...]

Circulation in Specific Vascular Beds

By Dr. Joseph H Volker | 2018-08-30T09:13:19+00:00 August 8th, 2018|Cardiovascular System, Physiology|0 Comments

Blood flow serves multiple functions. Matching of blood flow to metabolic needs is complex in organs that have variable metabolic rates, such as skeletal muscle. Local regulation of blood flow is well developed in tissues that have a low tolerance for ischemia, such as the brain and the heart. Some regional circulations serve functions other [...]
