Abducens (VI) - motor origin: pons term: lateral rectus -rotates eye laterally Accommodation - looking at an object up close -eyes converge ex) crossing -pupils constrict -lens changes: more curved (up close) Adaption of sensory receptors - most sensory receptors adapt, become less sensitive during prolonged time; Nociceptors and most proprioreceptors do not adapt Adrenergic neurons - secrete NE sympathetic postganglionic fibers 1. alpha adrenergenic: constrict blood vessels and dila...

Out of approximately 21,000 protein-coding genes in humans, how many are approoxiamtely devoted to cell signaling? Correct Answer-More than 7,000 What types of molecules can Signaling Molecules or Ligands be? (General Principle of Signaling) Correct Answer-Proteins, Peptides, Amino Acids, Nucleotides, Steroids, Fatty Acid Derivatives, Gases What must a cell have in order to accept a signal? (General Principle of Signaling) Correct Answer-A receptor What processes does the intracellular ...

Accesories of the Afferent Division of the Nervous system Correct Answer-1. Receptors - detects stimuli 2. Sensory neurons - relays sensory information towards the CNS *receives input from dendrites, uses axon to send it to CNS* 3. Sensory pathways - nerves, nuclei, and tracts that deliver sensory information to the CNS Accesories of the Efferent Division of the Nervous system Correct Answer-1. Nuclei - contain cell bodies of motor neurons 2. Motor neurons - send commands to effect...

OCCTH 583 Midterm Latest Update Graded A+ Dendrites Branchlike parts of a neuron that are specialized to receive information Cell Body / Soma The part of the neuron that contains the nucleus, which processes and integrates information Axon A threadlike extension of a neuron that carries nerve impulses away from the cell body A bundle of axons makes up a ___ Nerve Axon Collaterals Branches of the axon that allow one neuron to pass the signal to multiple effectors Where is t...

12 - how many cranial nerves? 2 effects of dual innervation - Antagonistic effects oppose each other: pupillary dilator and constrictor muscle, heart slowed down or speeded up Cooperative effects seen when 2 division act on different effectors to produce a unified effect 3 routes of sympathetic innervation - Spinal nerve route: effectors in body wall are innervated by sympathetic fibers that exit a ganglion by the gray ramus and travel through spinal nerves Sympathetic route: effectors in ...

2024 ASU BIO 340 {COMBINED EXAMS} LATEST QUESTIONS AND ANSWERS 100% VERIFIED What will be the effect on transcription when an inhibitor is in play? A. Allow transcription B. Prevent transcription - CORRECT ANSWER B Explanation: An inhibitor prevents activator from binding to DNA; activators are used in positive regulation (increasing transcription) - thus, the inhibitor prevents the activator from positive regulating (increasing) transcription. What will be the effect on transcription ...
