microvilli that project through pores and chemically sense food. Gustatory receptor cells communicate with cranial nerve axon endings to transmit sensation to the brain. There are five taste sensations located on the tongue. They are sweet located front middle‚ sour located middle sides‚ salty located front side/tip‚ bitter located back‚ and umami located posterior pharynx. The cranial nerves that are associated with our taste sense are VII Facial located within the tongue‚ IX Glossopharyngeal located

craniocaudally. A fifth and a 6th are also present but are very small. A primitive mouth appears as a small depression referred to as stomatodeum (stomodeum). The oropharyngeal (buccopharyngeal) membrane separates the stomatodeum from the primitive pharynx (cranial part of the foregut). This membrane ruptures at 24 to 26 days and communication with the amniotic cavity is established. Identify Rathke’s pouch in Picture 3 and review your notes on the subject.

communication network - coordinates and organizes 3 Division: 1. CNS- central nervous system - made up of the brain and the spinal cord 2. PNS- peripheral nervous system - includes nerves that connect the CNS to the remote body parts - relays and receives messages 3. ANS- autonomic nervous system - regulates the involuntary function of the internal organs. Histology: made up of 2 cells

Lab Report: Reflex and Special Senses Please fill out this report and submit it to the dropbox. Do not hand in your own form. It will not be graded and you will receive a zero for the lab. You must get all parts correct to get credit for the question * Please note that although you do not hand in items in observations‚ it is very important to do these as you may see some of these items on future/associated lab quizzes or be asked about some of these

Laboratory 3 Brainstem and Cranial Nerves Associated radiology modules: BRAINSTEM‚ CRANIAL NERVES Brainstem BLOOD SUPPLY The major blood supply to the brain is from two pairs of arteries‚ the vertebrals and the internal carotids. In general‚ the vertebrals supply the brainstem‚ the caudal diencephalon and the caudal and inferior cerebrum. The carotids supply the rostral thalamus and hypothalamus‚ the basal ganglia and the remainder of the cerebrum. Vertebral Branches. The vertebral arteries
Premium Neuroanatomy
a simple nerve circuit. A stimulus‚ such as a light tap with a rubber hammer‚ causes sensory neurons (nerve cells) to send signals to the spinal cord. There‚ the signals are conveyed both to the brainand to nerves that control muscles affected by the stimulus. Without any brain intervention‚ these muscles may respond to an appropriate stimulus by contracting. Reflex tests measure the presence and strength of a number ofreflexes. In so doing‚ they help to assess the integrity of the nerve circuits
