    Correct

    • Which neurotransmitter is released from the postganglionic fibers in the sympathetic division?

      Your Answer: Noradrenalin

      Explanation:

      Noradrenalin Is the neurotransmitter that is released from the postganglionic fibers of the sympathetic division. It is stored in granules at the sympathetic knobs. It Is a methyl derivative.

    Correct

    • Which ventral (motor) root is responsible for triceps?

      Your Answer: C7

      Explanation:

      Of the nerve fibers that make up the brachial plexus, C7 mainly forms the radial nerve to innervate the triceps muscle, thus innervating the shoulders, elbow, wrist and hand. C7 is responsible for the triceps reflex.

    Correct

    • The consensual light reflex is co-ordinated mainly in the:

      Your Answer: Edinger-Westphal nucleus

      Explanation:

      The consensual light reflex occurs when an individual’s right eye is shielded and light shines into the left eye, constriction of the right pupil will occur, as well as the left. This is because the afferent signal sent through one optic nerve connects to the Edinger-Westphal nucleus, whose axons run to both the right and the left oculomotor nerves.

    Incorrect

    • Regarding taste threshold and intensity discrimination:

      Your Answer: 90% change in concentration of substance tasted is necessary before an intensity difference can be detected

      Correct Answer: 30% change in concentration of substance tasted is necessary before an intensity difference can be detected

      Explanation:

      The ability of humans to differentiate differences in intensity of taste is poor. A 30% change in the concentration of the substance being tasted is required before an intensity difference is perceived.

    Incorrect

    • Which receptor type is associated with uterine contracture in pregnancy?

      Your Answer: Α2

      Correct Answer: Α1

      Explanation:

      Alpha-1 adrenergic receptors cause uterine contraction during pregnancy. They are linked to Gq-proteins that activate smooth muscle contraction through the IP3 signal transduction pathway.

    Correct

    • Which one of the following nerve fibers is involved in proprioception?

      Your Answer: An α fiber

      Explanation:

      Proprioception, also known as kinaesthesia, is the sense through which humans perceive their own position and movements. α nerve fibers are specifically involved in transmitting proprioception stimuli.
