Relative terms. Anterior-posterior and ventral-dorsal Anatomists, when considering the human body, refer to the head as superior, toward the feet as inferior, the front of the body as anterior or ventral and the back of the body as posterior or dorsal. Examples: •The sternum is anterior (ventral) to the heart •The heart is posterior(dorsal) to the sternum

Ventral Hernia What is a ventral hernia? A ventral hernia is a bulging of organs or abdominal tissue through a weak spot or opening in the abdominal wall. The abdominal wall is made up of fat and muscle. It holds the organs in place. What are the types of ventral hernias?

- A ventral hernia is a bulge through an abnormal opening in the wall of your abdominal muscles. The bulge is often part of your intestine, but it may also be tissue or fat. There are three common types of ventral hernias. An incisional hernia occurs where you have had a surgical cut.

Difference Between Dorsal and Ventral However, the ventral side is softer in texture compared to the dorsal side because the ventral side is instinctively or physically protected by the dorsal side. The ventral side bears external appendages in most of the animals; at least the external organs are directed towards the ventral side. Ventral side bears more external organs than the dorsal side usually does. • Usually, the dorsal side is hardy while the ventral side is tender.

I am NOT a computer buff. What does defrag mean and how do I do it. Simple language answer please.? Trending Now. Answers. Best Answer: Defrag, or disk defragmenter, is a software utility designed to help chronologically order the data on the hard disk drive. The theory behind defrag is to place each program together instead of scattered throughout the hard disk drive, allowing the read-write head to access the data faster on the hard disk drive. To defrag your hard disk please view the link below: Source(s): http://www.computerhope.com/software/defrag.htm.

What is a ventral nerve root? Ventral Nerve Root. Sections. A ventral root is a type of nerve root that branches off the spinal cord, exits the spinal column and continues on its path to specific areas of the body. At each level of the spinal cord, two nerve roots branch out, one to the left and one to the right. At the innermost base of each spinal nerve there are two roots, the ventral root (also called anterior root), and the dorsal root (also called the posterior root).

Ventral Hernia Ventral Hernia. Hernias most commonly develop in the abdominal wall, where an area weakens and develops a tear or hole. Abdominal tissue or part of the intestines may push through this weakened area, causing pain and potentially serious complications. Ventral hernias are a type of abdominal hernia. They may develop as a defect at birth, resulting from incomplete closure of part of the abdominal wall, or develop where an incision was made during an abdominal surgery, occurring when the incision doesn't heal properly.

What does effacement of the left ventral thecal sac and possible minmal flattening of left central cervical spinal cord at c5-c6 Left framinal stenosis particularly proximal at this level mean? Ventral means in front. Thecal sac means the sac that contain the spinal cord and cerebro spinal fluid. Effacement of the ventral thecal sac means pressure is upon the front of the sac (producing a flattening effect) most likely from a disc protrusion. Foramen means hole (where the nerve comes out of from the spinal cord). Stenosis means narrowing (usually from bony degeneration or disc herniation/protrusion/or bulge).

dorsal In veterinary anatomy, pertaining to the back or upper surface of an animal. Often used to indicate the position of one structure relative to another; that is, nearer the back surface of the body. 4. Old term meaning thoracic, in a limited sense; for example, dorsal vertebrae.

What would and what would not happen if only the ventral root of a spinal nerve were severed? (Include BOTH the âwouldâ and âwould notâ) The ventral root (anterior) of the spinal nerve is the front part of the spinal nerve. It consists of axons from neurons while cell body of the neurons is located in the white matter of the spinal column. The ventral root joins with the dorsal root (posterior) root to form the entire spinal nerve. The white matter, where the cell body is located is the 'computer' of the spinal nerve while the ventral root is the connections since it is composed of the axons of the neurons.

Anatomical terms of location These two terms refer to back (dorsal) and front or belly (ventral) of an organism. The dorsal (from Latin dorsum, meaning 'back') surface of an organism refers to the back, or upper side, of an organism. If talking about the skull, the dorsal side is the top.

Difference between neural tube and dorsal nerve cord? The dorsal nerve cord is later modified in vertebrates into the central nervous system which is composed of the brain and spinal cord. Dorsal nerve cord is mainly found in subphylum Vertebrata. Dorsal means the back side, as opposed to Ventral which is the front side of an organism. In organisms with Bipedalism dorsal is the back and ventral is the front. In organisms which walk on four limbs the dorsal surface is the top (back) and the ventral surface is the bottom (belly).

What Is the Difference Between Dorsal and Ventral? A: Dorsal refers to the back side of the body whereas ventral refers to the front side of the body. When discussing bipeds, these terms are interchangeable with the terms posterior and anterior.. These terms can become confusing when talking about both bipeds and quadrupeds.

Brightest Stars: Luminosity & Magnitude While many stars have a consistent brightness, there are more than 100,000 known and cataloged variable stars. (Even our own sun is variable, varying its energy output by about 0.1 percent, or one-thousandth of its magnitude, during its 11-year solar cycle.)

- A - the biological sciences use the terms dorsal, ventral, anterior, and posterior to refer to direction within the body of a bilaterally symmetrical organism. These terms are illustrated in the photo on the right. Body parts on the sides of a body are referred to as being lateral.

Terminology Proximal and distal. Proximal refers to the end of a structure nearest a major point of reference and distal to the end furthest from a point of reference. The point of reference is usually the origin of a structure (such as a limb) or the ventral midline of the body. Proximal and distal are relative terms.These terms are correctly used to describe relative positions of structures in the limbs. Medial and lateral.ranial refers to the head end and caudal to the tail end. Anterior and posterior. In a quadruped the terms are synonymous with cranial and caudal. In a biped (Homo) anterior is used to indicate the ventral surface and posterior to indicate the dorsal surface.

- The ventral root contains efferent (motor) fibers that carry messages from the spinal cord to the effectors. Cell bodies of the efferent fibers reside in the spinal cord gray matter. These roots become nerves that innervate (transmit nerve impulses to) muscles and organs throughout the body.he perikaryon (cell body) is the neuron central part. Dendrites, short branches, extend from the neuron. These input channels receive information from other neurons or sensory cells (cells that receive information from the environment).

The ventral cavity, which it's… located along the FRONT of the body, contains the body organs that maintain homeostasis.

Ventral body cavity Human body cavities: Ventral body cavity is to the right. The ventral body cavity is a human body cavity that is in the anterior (front) aspect of the human body. It is made up of the thoracic cavity, and the abdominopelvic cavity.The abdominopelvic cavity is further divided into the abdominal cavity and pelvic cavity, but there is no physical barrier between the two.he thoracic cavity is further separated into the pleural cavity which contains the lungs and the superior mediastinum which includes the pericardial (heart) cavity. The organs within the ventral body cavity are called the viscera.
