The frontal plane: Also referred to as the coronal plane, separates the front from the back of the body. These 4 chambers are divided into 2 functional units referred to as the left heart and the right heart. These smooth and rough tubes and the ribosomes within play a role in the synthesis or manufacture of protein and lipids. There was an error retrieving your Wish Lists. The sum of blood flow to these individual systems adds up to the total left ventricular output (the cardiac output). Smooth muscle, in sharp contrast to skeletal muscle, is not striated and it is not under voluntary control Smooth muscle is found in the digestive system where it performs peristalsis and it is also found in other organs and systems such as the vascular system where it dilates and constricts blood vessels, all of which are involuntary muscular activities. During systole, the right ventricle pumps this deoxygenated blood out of the heart and into the pulmonary circuit via the pulmonary artery*. An example of a fluid connective tissue is blood which is surrounded with plasma, the matrix for this type of connective tissue. For example, the nipple is medial to the shoulder.

Meiosis consists of several phases, as shown in the picture above, that include the: Meiosis is the process that occurs during the fertilization of the ovum with sperm. The frontal plane, also referred to as the coronal plane, which is shown in the picture above, is the imaginary line that separates the front from the back of the body. The somatic nervous system has efferent nerves which send and receive motor function related nerve signals and also efferent nerves which send and receive sensory function related nerve signals. The aorta divides into large and medium sized arteries, which eventually give arise the arterioles. Homeostasis A process of maintenance of the nearly constant internal environment. The stages of mitosis in the correct sequential order, as shown in the picture above, are: The table below summarizes the differences between meiosis and mitosis, The regeneration of the skin's epithelial cells, Haploid cells with half of the chromosomes that the parent cell has, Diploid cells with the same number of chromosomes as the parent cell has, Crossing over occurs to provide genetic variation, No crossing over; homologous chromosomes remain, Genetic differences when compared to the parent cells, Identical genetic information as the parent cells. There's a problem loading this menu right now. The arterioles continue to form capillaries, and these capillaries merge together to form venules at their venous ends.

She got her bachelor’s of science in nursing with Excelsior College, a part of the New York State University and immediately upon graduation she began graduate school at Adelphi University on Long Island, New York. not clinical // no diseases II. Mitosis, a form of asexual replication, occurs when the nucleus of the cell replicates itself into two identical copies of itself. Please try again. The term posterior is a relative and comparative directional term that is used to describe that a bodily part or anatomical structure is further behind another bodily part or anatomical structure. What makes the anatomical position different from a normal standing position is the fact that the palms of the hands are unnaturally facing forward rather than naturally facing the leg, as you can see in the picture above. For example, muscle is deeper than the skin. Coined by Sir Walter Cannon, an American Physiologist. Save my name, email, and website in this browser for the next time I comment.

Similarly, the term inferior is a relative and comparative directional term that is used to describe that a bodily part or anatomical structure is below another bodily part or anatomical structure. HEART AS 2 PUMPS: The human heart has 4 chambers which are the two atria and the two ventricles. For example, as you look at the human body with the naked eye, you will see its interior when the inner parts of the body are exposed, and you will see the exterior of the intact body. Two gametes fuse during fertilization, creating a diploid cell with a complete set of paired chromosomes. The cytoskeleton, similar to the skeletal system of the body, is made of protein and it maintains the shape and form of the cell so that it does not collapse as parts of the cell move about and the cell itself moves about. The cells of the human, animals and plants are examples of eukaryote cells. My greatest hobby is to teach and motivate other peoples to do whatever they wanna do in life. As shown in the picture above there are three types of muscle tissue which are: Skeletal muscle, which is also referred to striated muscle, is muscle that enables voluntary bodily movement. Does Cannabis Oil Treats Cancer? Exercise increases the percentage of cardiac output which is made available for the skeletal system.

From the smallest to the largest part of the human anatomy, in that sequential order, are the: Below are some terms relating to anatomy, anatomical structures and anatomical directions that you must be familiar with. Unable to add item to List. The type of tissue that is surrounded with what is called its matrix, as shown in the picture below: Section of epididymis. Cell nucleus: The place in the cell that contains chromosomes and the place where both DNA and RNA are synthesized and replicated. Tissues are a collection or group of cells with similar structures that join to form a tissue with a distinct purpose and function. It’s important to remember that all the valves of the heart are tricuspid i.e., having three cusps, except the mitral valve which is bicuspid i.e., having two cusps. Passive transport is the movement of molecules across membranes that does NOT require the use of cellular energy to perform this transport. Some living organisms like the amoeba and the paramecium are one celled, or unicellular, living bodies, but, for the most part, living organisms are made up of trillions and trillions of cells. March 12th 2015 The right side of the heart deals with deoxygenated blood only and it functions to send this deoxygenated blood to the pulmonary circulation to get oxygenated.

Coronal/ Frontal plane – A plane which divides the body into anterior and posterior halves is called the coronal plane. Some of the physiological functions under the control of the autonomic, or automatic, nervous system are the movements of smooth, involuntary muscles, in contrast to voluntary skeletal muscles, like those that create peristalsis in the digestive system and the constriction of the eye's pupil when it is exposed to light. The term used for the front of the body is the ventral surface and the term used for the back of the body is the dorsal surface of the body. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Supporting connective tissue lies in a highly firm matrix to support the body and bodily parts.
