Peripheral Nervous System (PNS) – Cranial Nerves and it’s Reflexes

By Dr. Joseph H Volker | 2018-08-30T11:09:52+00:00 August 8th, 2018|Anatomy, Body Systems, Nervous system, Physiology|0 Comments

The peripheral nervous system (PNS) consists of cranial and spinal nerves that connect the CNS to other portions of the body, along with sensory receptors and ganglia. A nerve consists of axons that are bound together by connective tissue. Motor nerves contain mostly axons of motor neurons; sensory nerves contain only axons of sensory neurons; [...]

Autonomic Nervous System (ANS)

By Dr. Joseph H Volker | 2018-08-30T11:11:03+00:00 August 8th, 2018|Anatomy, Body Systems, Nervous system, Physiology|0 Comments

The ANS is a major mechanism for neural control of physiologic functions. The autonomic nervous system (ANS) consists of portions of the central and peripheral nervous systems and functions without conscious control. Discussions of ANS usually take one of three perspectives: An anatomic perspective based on structure, A physiologic perspective based on function, A pharmacologic [...]

Respiratory System – Structures and Functions

By Dr. Joseph H Volker | 2018-08-30T09:39:08+00:00 August 8th, 2018|Anatomy, Body Systems, Physiology, Respiratory System|0 Comments

THE PRIMARY ROLE of the respiratory system is to make oxygen available to cells for cellular respiration and to remove carbon dioxide, the main byproduct of that metabolism. The entire process of respiration encompasses five unique and sequential processes: Breathing (pulmonary ventilation)-the movement of air into and out of the lungs. Alveolar gas [...]

Urinary And Renal System: Anatomy, Physiology, Structure and Function

By Dr. Joseph H Volker | 2018-08-30T10:03:06+00:00 August 8th, 2018|Anatomy, Body Systems, Physiology, Renal System|0 Comments

The renal system consists of the kidneys, ureters, bladder, and urethra. The kidney contains the nephron, the functional unit of the renal system. The nephron consists of the glomerular and peritubular capillaries and the associated tubular segments. The glomerular tuft (glomerulus) contains capillaries and the beginning of the tubule system, Bowman's capsule. Tubule fluid, an [...]

Male Reproductive System – Locations and Functions of the Male Reproductive Organs

By Dr. Joseph H Volker | 2018-08-30T10:25:09+00:00 August 8th, 2018|Anatomy, Body Systems, Physiology, Reproductive System|0 Comments

The primary functions of the male reproductive system are the production of male sex hormones, the formation of sperm, and the placement of sperm in the female reproductive tract, where one sperm can unite with a female sex cell. The organs of the male reproductive system include (1) paired testes, which produce sperm and male [...]

Female Reproductive System – Locations and Functions of the Female Reproductive Organs

By Dr. Joseph H Volker | 2018-08-30T10:32:50+00:00 August 8th, 2018|Anatomy, Body Systems, Physiology, Reproductive System|0 Comments

The female reproductive system produces female sex hormones and female sex cells and transports the sex cells to a site where they may unite with sperm. In addition, the female reproductive system provides a suitable environment for the development of the embryo and fetus and is actively involved in the birth process. The organs of [...]

Limbic System

By Dr. Joseph H Volker | 2018-08-30T10:53:52+00:00 August 8th, 2018|Anatomy, Body Systems|0 Comments

The word limbus means ring, the term limbic system is applied to the parts of the cortical and subcortical structures that create a ring around the upper end of the brainstem. The limbic region was formerly referred to as rhinencephalon because of its association to olfaction, however only a small part of it is truly [...]

Human Skeletal System

By Dr. Joseph H Volker | 2018-08-30T09:23:02+00:00 August 8th, 2018|Anatomy, Body Systems|0 Comments

The basic structure of human body is skeletal system. The entire body is built around the hard framework of Skeleton. At birth around 270 bones are present, by adulthood this total decreases to around 206 bones when bones merge together. About the age of 21 the bone density within the skeleton achieves its full density. [...]
