Each arrector pili is composed of a bundle of smooth muscle fibres which attach to several follicles a follicular unit , and is innervated by the sympathetic branch of the autonomic nervous system . The contraction of the muscle is therefore involuntary stresses such as cold, fear etc. may stimulate the sympathetic nervous system and thus cause contraction, but the muscle is not under conscious control. Contraction of the muscles has a number of different purposes. Its principal function in the majority of mammals is to provide insulation air becomes trapped between the erect hairs, helping the animal retain heat. Erection of the porcupine s long, thick hairs causes the animal to become more intimidating, scaring predators. Pressure exerted by the muscle may cause sebum to be forced along the hair follicle towards the surface, protecting the hair. The effectiveness of the muscles action in humans has been questioned, as humans have relatively little body hair to allow for thermal insulation.

Merge Constantio Varoli date February 2009 Image Varolio illus.png right thumb Illustration from De Nervis Opticis by Varolius Costanzo Varolio , Latinized as Constantius Varolius , born Bologna , 1543 died Rome , 1575 was an Italian anatomist and a papal physician to Gregory XIII . ref Mandosio disputed by Marini ref He was a pupil to the anatomist Giulio Cesare Aranzio , himself a pupil of Vesalius . He received his doctorate in medicine in 1567. In 1569 the Senate of the University of Bologna created an extraordinary chair in surgery for him with responsibility to teach anatomy as well and where a statue of him is housed at the Anatomical Theatre of the Archiginnasio . Later he is believed to have taught at the Sapienza University of Rome although he is not listed on the role there. Nevertheless, he is known to have had considerable success in Rome both as a physician and as a surgeon and his memorial plaque in that city refers to his great skill in removing stones. He is best remembered for his work on the cranial nerves . He was the first to examine the brain from its base upwards, in contrast with previous dissections which had been performed from the top downwards. In 1573 he published this new method of dissecting the brain whereby he separated the brain from the skull and began the dissection from the base. Varolio described many of the brain s structures for the first time including the pons or pons Varolii which is a reflex center of respiration and a communication bridge between spinal cord and brain, the Cerebral crus crura cerebri and the ileocecal valve . ref MARTINOTTI G. 1926 , Costanzo Varolio e il suo metodo di sezionare l encefalo.
