Cranial Nerves The human body is a unique and fascinating entity. There is not much notice taken of the features the human body is capable of. The brain is necessary to perform day-to-day actions‚ such as the ability to speak‚ and see amongst us. This brain is made up of simple mater (Pia mater‚ Arachnoid mater‚ Dura mater) and the cranial surface to protect the brain. We live our daily lives without acknowledging the importance of this organ‚ the brain‚ unless you’re a medical student of

taste buds (mushroom like projections) which are specific receptors for sense of taste. Each bud contains several cell types in 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

Axon the long thin tube structure that take the information sent from the soma to the terminal buttons and the terminal buttons are small knob structure at the end of each branch of the axon. These buttons discharge neurotransmitters. The forebrain is made up of the telencephalon and the diencephalon. The midbrain comprises of mesencephalon which

Humans have a blind spot because the spot that the axons meet to form the optic nerve does not have any sensor cells. 2. Describe the functional and anatomical differences between rods and cones: a. Rods: Respond to faint light and are more abundant in the periphery of the eye. Cylindrical shape‚ similar to a welding rod. b. Cones: Responsible for color vision

changes that underlie learning and memory. This occurs when the synapse is active and the postsynaptic cell is depolarized. Cells that lead to the synapse onto the dentate granular cells are called DG cells which then send axons to CA3. CA3 cells are responsible for sending axons to CA1 output cells. LTP has four crucial steps to making the process obtainable. One glutamate the neurotransmitter to the CNS is released allowing acts on both AMPA and NMDA receptors. Sodium receptors are then able to flow
