Reticular formation The reticular formation (lat. formatio reticularis) is a set of interconnected nuclei that are located throughout the brainstem.The reticular formation is not anatomically well defined because it includes neurons located in diverse parts of the brain.The neurons of the reticular formation all play a crucial role in maintaining behavioral arousal and consciousness. The functions of the reticular formation are modulatory and premotor.The modulatory functions are primarily found in the rostral sector of the reticular formation and the premotor functions are localized in the neurons in more caudal regions.he functions of the reticular formation are modulatory and premotor. The modulatory functions are primarily found in the rostral sector of the reticular formation and the premotor functions are localized in the neurons in more caudal regions.

Reticular formation The reticular nucleus of the thalamus (not pictured) has nothing to do with the reticular formation; its naming was a coincidence. This nucleus wraps around the thalamus, forming a thin net, for which it is named (reticular means netlike or an intricate network).

Reticular connective tissue Reticular connective tissue is a type of connective tissue. It has a network of reticular fibers, made of type III collagen.Reticular fibers are not unique to reticular connective tissue, but only in this type are they dominant. Reticular fibers are synthesized by special fibroblasts called reticular cells.here are more than 20 types of reticular fibers. In Reticular Connective Tissue type III collagen/reticular fiber (100-150 nm in diameter) is the major fiber component. It forms the architectural framework of: liver, adipose tissue, bone marrow, spleen and basement membrane, to name a few.

Chapter 6 - Brain Stem Organization The paramedian pontine reticular formation (PPRF) has particular involvement in horizontal eye movements. There are connections with various cranial nerve nuclei and patterned reflex responses (like blink and gag) and complex responses (like vomiting, coughing and swallowing) all have centers within the brain stem.

- Reticulate evolution, also network evolution, describes the origination of a lineage through the partial merging of two ancestor lineages, leading to relationships better described by a phylogenetic network than a bifurcating tree.[1]

Reticular fiber The term reticulin was coined in 1892 by M. Siegfried. Today, the term reticulin or reticular fiber is restricted to referring to fibers composed of type III collagen. However, during the pre-molecular era, there was confusion in the use of the term 'reticulin', which was used to describe two structures:

Reticular formation The reticular formation is a part of the brain which is involved in stereotypical actions, such as walking, sleeping, and lying down.It is absolutely essential for life.unctions Edit. The reticular formation is an important regulator in the autonomic nervous system for such processes as respiration rate, heart rate and gastrointestinal activity. It also plays an important role in sleep and consciousness as well as modulation of pain.

Medical Dictionary A reticulocyte count is a blood test that measures how fast red blood cells called reticulocytes are made by the bone marrow and released into the blood. Normal. The reticulocyte count is given as the percentage of red blood cells that are reticulocytes (the number of reticulocytes divided by the total number of red blood cells, multiplied by 100).

Reticular Formation: Definition & Functions The reticular formation has two main components: the ascending and the descending reticular formation. The ascending reticular formation is responsible for sleep cycles and is also called reticular activating system. The descending reticular formation affects your posture and autonomic nervous system functioning. Certain nuclei are also responsible for eye movements, coughing, chewing, swallowing, and vomiting.
