Who was the first to discover the human brain

Rufus of Ephesus

Explanation:

By the first century A. D., Alexandrian anatomists such as Rufus of Ephesus had provided a general physical description of the brain.  Basic structures such as the pia mater and dura mater (the soft and hard layers encasing the brain) were identified in addition to the basic divisions of the brain itself. Building upon this research in the next century, the Roman physician Galen concluded that mental actively occurred in the brain rather than the heart, as Aristotle had suggested.  His observations of the effects of brain injuries on mental activity formed an important practical basis for his conclusions.  Galen concluded that the brain was the seat of the animal soul -- one of three "souls" found in the body, each associated with a principal organ.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.

homeostasis is the tendency towards a relatively stable equilibrium between interdependent elements, especially as maintained by physiological processes. and this is how it applies to the integumentary system. back to top. skin functions in homeostasis include protection, regulation of body temperature, sensory reception, water balance, synthesis of vitamins and hormones, and absorption of materials. when body temperature falls, the sweat glands constrict and sweat production decreases.
