Discuss the process of formation, shaping, folding, and closing of the neural plate.
Step by step
Solved in 3 steps
- Define the general function of neuralgia.Match each cranial nerve with the type of information it carries (sensory, motor, or mixed). CN I (olfactory nerve) CN II (optic nerve) CN III (oculomotor nerve) CN IV (trochlear nerve) CN V (trigeminal nerve) CN VI (abducens nerve) CN VII (facial nerve) CN VIII (vestibulocochlear nerve) CN IX (glossopharyngeal nerve) CN X (vagus nerve) CN XI (spinal accessory nerve) CN XII (hypoglossal nerve)Distinguish between the pia mater, arachnoid mater, and dura mater.
- Discuss the Neural Growth and Regeneration of the cells of the nerveous system?Describe structure and provide a generalized function for each of the following regions of the brain: brain stem, diencephalon, cerebrum, cerebellum.Identify the three major regions of the brain stem, and note the functions of each area.
- Give the brain region for the functions described. 1. Contains vital centers that regulate heartbeat, breathing, blood pressure, vomiting, coughing 2. Smoothes and coordinates skilled skeletal muscle movement; also posture and balance or equilibrium 3. Secretes melatonin that controls the sleep-wake cycle 4. Controls and integrates the autonomic nervous system; regulates hormones, emotional behavior, temperature, eating, and drinking behavior 5. Interprets sensory input, controls skilled skeletal muscle movements, and is involved in emotional and intellectual processes 6. Helps control breathing; conducts impulses to and from the cerebellum, midbrain, and medulla 7. Relays all sensory input to the cerebral cortex; involved in skeletal muscle actions and memory processing 8. Coordinates visual and auditory reflexes 9. Coordinates gross, automatic muscle movements; also involved with the limbic system 10. White fiber tracts communicating between hemispheresTrace the major neuronal pathways to and from the brain. Include the name of the Pathway (or Tract), whether the tract is ascending (sensory) or descending (motor), what it basically does (e.g. type of stimulus) , and where it decussates (i.e. crosses the midline, which not all cross).b. Label the figure indicating the steps involved in neural transmission (use the key terms provided in the box below the figure) 1 Synthesizing enzymes Neurotransmitter precursors Vesicle Neurotransmitter molecules that leak from their vesicles are destroyed by enzymes. Degrading enzymes 4 E Released neurotransmitter molecules bind with autore- ceptors and inhibit subsequent neurotransmitter release. 6. Autoreceptor Postsynaptic receptor A. Neurotransmitter molecules are stored in vesicles B. Released neurotransmitter molecules are deactivated by reuptake C. Action potentials cause vesicles to fuse with the presynaptic membrane and release their neurotransmitter molecules into the synaptic cleft D. Neurotransmitter molecules are synthesized from precursors under the influence of enzymes E. Released neurotransmitter molecules bind to postsynaptic receptors
