Answer
The reticular formation (RF) is a network of neurons and nuclei that is spread through the brain stem. The diffuse nature of the system makes it simpler to conceive of it as a functional entity.
Three bands of nuclei along the brain stem are included in the reticular formation:
1. The median raphe nucleus
2. The medial nuclei group
3. The lateral nuclei group
Work Step by Step
The reticular formation is a diffuse set of nuclei that extend through the brain stem.
The three principal groups in the reticular formation are the raphe nucleus, the medial nuclei group and the lateral group of nucle
The raphe nucleus produces serotonin ( a mood hormone); the medial nuclei are concerned with muscle coordination, and the lateral group of nuclei are concerned with the process of exhalation.
The the neurons of the reticular formation are in diverse parts of the brain including the hypothalamus, the thalamus, the cerebral cortex and the cerebellum. The general functions of the network are to control posture,, coordinate eye muscles, moderate pain, monitor and control respiratory and cardiac activity, and maintain consciousness and attention.
