Physiological processes lead to anatomical changes in the body. Soil temperatures affect the anatomical and morphological character of root systems. Along with homologous physiological, sensory, anatomical and signal-transduction mechanism similar to mammals. Pituitary adenomas are classified based upon anatomical, histological and functional criteria. It is separate from anatomical pathology and clinical pathology. Traditionally, tetrapods are divided into four classes based on gross anatomical and physiological traits. The primary anatomical and functional unit of cancellous bone is the trabecula. It deals with the anatomical, histological and embryologic terminology. These muscles are described using anatomical terminology. Each of these components has a complex internal anatomical and neurochemical organization. It also assists scientists in classifying organisms based on similar characteristics of their anatomical structures. By using precise anatomical terminology such ambiguity is eliminated. Such classifications depended mainly on appearance and anatomical characteristics. Neuropsychology describes the dependence of mental faculties on specific anatomical regions of the brain. Studies based on anatomical, embryological, and paleontological data have produced different "family trees".
