Sensory division of nervous system is also called as afferent division. It has nerves that come from sensory receptors present in internal organs and somatic areas ( eyes, ears, skin etc. ) and these nerves send impulse to CNS. CNS gets information on what is happening with the body via these impulses. It can detect various senses like touch, hearing, sight etc.
In contrast motor or efferent division of nervous system conducts impulse from CNS to effector body parts which decide how the body responds to a stimulus.
The seminal vesicles produce about 70% of seminal fluid, consisting mostly of fructose and amino acids. 30% of the fluids are made in the prostate, which consists of proteolytic enzymes, citric acid, acid phosphatase, and lipids. The bulbourethretous glands produce a minimal amount of fluids, to help lubricate the lumen of the urethra.
