Essay The Correlation Among Brain Anatomy And Physiology
Overview of structure & function
The brain of humans is primarily composed of two general classes of cells; neurons and glial cells. Glial cells have a wide range of varieties, and implement numerous roles, including development, metabolic support, insulation, and structural support. Neurons, about 100 billion in number, is are electrically excitable cells that route and process information through electrical and chemical signals. The most common neurons are structurally designed to consist of a soma (cell body), dendrites that branched tree like projections from a soma, and axon which is the slender projection connected to the soma.
The superior most regions of the brain is identified as the cerebrum. The cerebrum is not only the largest structure in the brain, but it also includes the most commonly recognized characteristic of the brain; sulci and gyri of the cerebral cortex. The cerebral cortex is divided into two cortices along a mid-sagittal plane called the medial longitudinal fissure. This fissure separates the brain into the left and right hemispheres. Subcortical…
