Physiology is a field of knowledge that deals in the study of functioning of living things. This is in respect to the discipline of science. This study is usually about organisms and the functioning of their organs. The study also focuses on functioning of cells such as biochemical processes that take place in the cells. The study is broken down into sub groups such as physiology of plants, physiology of cells, physiology of virus, physiology of bacteria and the physiology of animals including human being. Human physiology is the earliest study in the field of physiology and most probably, it began in India. According to history, the field of physiology was developed by fields such as Cell theory, Ecophysiology, Evolutionary physiology and Comparative physiology which were the works of scientists such as George Bartholomew and Walter Cannon.
This is the study of cell anatomy of both plants and animals. Histology is done by observing cell structures by use of a powerful microscope such as an Electron Microscope. The common method used to carry out the study is known as Tissue Culture. In this method, a cell, which is alive, is segregated and kept in a favorable environment for research purposes.
Historadiography is a radioactive procedure for examining samples of histology. Radioactive substances can be located in the body by use of Autoradiography technique. Therefore, histology is significant in medicine. In cases such as treatment of cancer, histopathology can be used to analyze the samples of histology. Medical personnel who carry out histopathology should be physicians who have been certified by medical boards to be qualified pathologists.
This is a branch of science particularly in pathology that deals with study of cells especially cell structure and functions. The study focuses on diagnosing a disease (s) by analysis of body tissues. Body tissues include fluids from the body such as blood and urine. A pathologist is someone who has vast knowledge in cytology. Powerful microscopes such as the Electron Microscope is used in examination of the cells. The material containing the cells to be examined is placed on glass sides which are then mounted on the stage of the microscope.
This is a branch of life science in the field of physiology that deals with the study of working of the nervous system. Neurophysiology mostly focuses on the science of the brain. The study is associated with other sciences such as neurobiology, neurology, biophysics, neuroanatomy and psychology. The basis of the study include; molecular biology, calcium imaging and patch clamp.
Gross (macroscopic) anatomy
This scientific field deals with analysis of body parts of living organisms. The study involves observation of the body parts by use of naked eyes. There are different methods used to study gross anatomy such as Dissection, examining real body parts of an animal, and Endoscopy, where a powerful digital camera helps reveal minute structures. There are two methods used to study Gross (macroscopic) anatomy. The methods are Invasive and non-invasive and have the main aim of understanding both the way organs have been organized and the structure of the organs and system of the organs.
