These systems work together to maintain your overall health. Some of the body systems are as below : Cardiovascular System • Consists of the Heart‚ Blood Vessels (Veins‚ Arteries‚ Capillaries) and Blood. Its main function is to

The Nervous System II: Ion Channels 1. List four neurotransmitters that bind to ion channels‚ these neurotransmitters are called __directly____-acting neurotransmitters. a. ACh b. glutamate c. GABA d. Glycine 2. a. The binding of ACh opens ion channels in the dendrites or cell body that permits both _sodium______ and _potassium____ to move through them. b. Which ion would move into the cell? _sodium____out of the cell? _potassium_____________ c. Which ion has the greatest electrochemical

Anatomy review for the nervous system - Week 12 Study Guide 1. Distinguish the difference between neuron‚ neuroglial cells‚ Schwann cells‚ neurofibrils‚ and astrocytes. Neuron: masses of nerve cells in nervous tissue Neuroglial Cells: provide neurons physiological requirements (fill spaces‚ give support to neurons) Schwann Cells: larger axons of peripheral neurons enclosed in sheaths Neurofibrils: thin‚ long fibrils that run through body of neuron and extends to axon and dendrites; gives neuron

Trigeminal nerve The trigeminal nerve is the fifth of twelve pairs of cranial nerves enervating the face and head‚ and is denoted by the Roman Numeral V. It has three divisions which enervate the forehead and eye (ophthalmic V1)‚ cheek (maxillary V2) and lower face and jaw (mandibular V3). The trigeminal nerves function in sensing facial touch‚ pain and temperature‚ as well as controlling muscles used for chewing. The trigeminal nerve functions should be distinguished from the facial nerve (cranial

Nerve and neuron sound similar to most people‚ but they are two different components of the body (Martini‚ 375). Nerves are found only in the peripheral nervous system‚ while neurons are found in the brain‚ spinal cord‚ and peripheral nerve (Martini‚ 375). Neurons are nerves cells that are specialized for intercellular communication (Martini‚ 375). A neuron is composed of a cell body‚ dendrites and axon (Marieb‚ 376). A nerve is a bundle of axons or dendrites that is wrapped in connective tissues

Nervous System I: Ion Channels 1. What structures in the cell membrane function as ion channels? Integral Proteins 2. Ion channels are selective for specific ions. What three characteristics of the ions are important for this selectivity? 1. Charge 2. Size 3. Amount of water the ion attracts 3. Channels can be classified as either gated or nongated channels. A sodium channel that is always open would be classified as a/an __________nongated______________ channel. 4. Would sodium ions

Optic Nerve The optic nerve is located in the back of the eye and is also called second cranial nerve and cranial nerve II. the optic nerve is to transfer visual information from the retina to teh vision centres of the brain via electrical impulses. It is made up of ganglionic cells or nerve cells and consists of more than 1 million nerve fibres . Our blind spot is caused by the absence of specialised photosensitive/light-sensitive cells or photoreceptors; the part of the retina where the optic
