Summary Introduction

To explain: How adrenal medulla is able to produce effects throughout the body even though it receives input only from sympathetic nervous system and pre-ganglionic neurons.

Concept introduction:

Preganglionic fiber terminates in a ganglion. There are axons from sympathetic neurons that reach the adrenal medulla which is the inner portion of the adrenal gland.

15. Match the neurotransmitter to its description:___________________________________Usually inhibitory; inhibits pain; released only in CNS___________________________________Usually excitatory; release is blocked by botulinum toxin; released at synapses in both the CNS and PNS; has nicotinic receptors on skeletal muscles at the NMJ; has muscarinic receptors at visceral organs and in the CNS.___________________________________Can be excitatory or inhibitory depending on where it is released and its target. Produced by the substantia nigra in midbrain; also by hypothalamus, etc.; “feel good” neurotransmitter; people with Parkinson’s disease have a deficiency of this. Plays a role in moderating motor impulses to skeletal muscles. Released mostly in the CNS.___________________________________Usually inhibitory. Released in the CNS. Plays a role in mood regulation.___________________________________Released in CNS, including spinal cord. It is the major excitatory neurotransmitter;…

15. All of the followings are incorrect, except ---------------------. A. Axons of preganglionic sympathetic neurons are short, with long postganglionic neuron axons B. Axons of preganglionic parasympathetic neurons are short C. All preganglionic sympathetic synapse in the sympathetic chain ganglia D. Parasympathetic ganglia are located in the cranial and the sacral part of the central nervous system E. In the sweat glands of the skin, the sympathetic neurotransmitter is Norepinephrine 16. A tap on the patellar tendon at the knee joint is used to test the knee-jerk reflex. All of the followings are incorrect, except ---------------------. A. This reflex involves relatively simple neuronal circuits B. The reflex starts with the 1a sensory neurons of the muscle tendon C. There is an inhibitory stimulus to the motor pool of the extensor muscle D. There is a stimulation of the excitatory interneuron of the flexor muscle E. Excitation of the flexor muscle fibers causes the knee extension…
