Physiology Quiz - How many are there in the human body? - Part 1
In order to have a complete understanding of physiological processes, it is often necessary to know gross anatomy as well as microscopic anatomy (i.e., histology). Often, it is important to know the number of a given structure under consideration. For example, a student of physiology should know the number of kidneys, nephrons, adrenal glands, cranial nerves, lungs, alveoli, etc. in the human body. Test your basic knowledge by taking this simple quiz.
(1) Approximately, how many cells are there in total in the body of an adult human being?
(2) Approximately, how many taste buds are there in the human oral cavity? While most of the taste buds are on the tongue, some are in the palate, tonsils, epiglottis, and even proximal esophagus.
(3) Approximately, how many alveoli are there in both (i.e., left and right) human lungs combined?
(4) Approximately, how many nephrons are there in both human kidneys combined?
(5) How many cranial nerves are there in the human nervous system?
(6) How many spinal nerves are there in the human nervous system?
