Answer:
The correct answer is: a. directs somatic motor axons to four of the six extrinsic eye muscles and also transmits parasympathetic visceromotor impulses to pupillary constrictor muscle of the eye.
Explanation:
<u>The </u><u>oculomotor nerve </u><u>(III) is the third cranial nerve.</u> It provides motor innervation to four of the six extrinsic muscles of the eye and has also a parasympathetic component in charge of contracting the pupil when the environment is rich in light.
The cranial nerve that innervates the lateral rectus muscles of the eye is the abducens nerve (VI).
The cranial nerve that provides motor innervation to the superior oblique muscle of the eye is the trochlear nerve (IV).
Answer:
b. dorsal column system
Explanation:
The backbone system is responsible for the sensation of touch and proprioception (which is the ability to recognize the spatial location of the body, its position and orientation, the force exerted by the muscles and the position of each body part relative to the others).
This system transmits information outside the body to a region called the postcentral gyrus in the cerebral cortex, which transmits stimuli, sensed by the body, to the brain.

Answer:
Consistently changes the subject when the topic of the fetus/newborn is raised.
Explanation:
This is the decision of the couple whether they want a child or not and can discuss about the family planning as well. Different psychological aspects acn explain this matter.
The expectant father is not mentally prepared for the child. He might refuse the talks and stay away from the communication that are related to the new born child. This must be properly assessed and important to understand the feeling of the expectant father.
Thus, the answer is consistently changes the subject when the topic of the fetus/newborn is raised.
Answer:
In chemical transmission the release of chemical messengers known as neurotransmitters occurs. Neurotransmitters carry information from the presynaptic or transmitter neuron to the postsynaptic or recipient cell.
As you may recall from the article on the structure and function of the neuron, synapses are usually formed between the nerve terminals - axon terminals - of the sending neuron and the cell body or dendrites of the receiving neuron.
Scheme of synaptic transmission. An action potential travels through the axon of the presynaptic or emitting cell, and reaches multiple axon terminals branching from the axon. The axon terminal is adjacent to the dendrite of the postsynaptic or recipient cell. This place of close connection between axon and dendrite is the synapse.
A single axon can have multiple ramifications, which allows it to synapse with several postsynaptic cells. Similarly, a single neuron can receive miles of synaptic inputs from many different presynaptic or emitting neurons.
Within the axon terminal of a transmitter cell there are many synaptic vesicles. These are membranous spheres full of neurotransmitter molecules. There is a small space between the axon terminal of the presynaptic neuron and the postsynaptic cell membrane, this space is called synaptic space.
