Homework Answers
Answer:
1. D) B1 adrenergic
Explanation: B1 is present on the heart causing increase n heart rate and contractility.
B2 receptors are present on the smooth muscles of the lungs and vessels causing bronchodilation and vasodilation.
2. D) Motor neuron
Explanation:
Five components of reflex arc are :
1) Receptor: a specialized part of a neuron that receives a signal.
2) Afferent / sensory neuron: a neuron that transmits the signal to the spinal cord.
3) Interneuron: a neuron in the spinal cord that connects input to output.
4) Efferent/ Motor neuron: a neuron that transmits the signal to the effector.
5) Effector: the tissue that turns the signal into action, usually a muscle.
3. D) Short preganglionic fibers and long postganglionic fibers
Explanation: Sympathetic fibers have short preganglionic fibers that lie synapse just near to the spinal cord in the sympathetic ganglia and then long postsynaptic fiber arises.
4. E) Both motor and sensory neurons
5. E) B2 adrenergic
6. E) Acetylcholine only
7. D) autonomic reflexes
Explanation: Autonomic reflexes are unconscious motor reflexes relayed from the organs and glands to the CNS through visceral afferent signaling.
