THE LIVING BODY1AbstractA human body works as a system made up of other small functioning units which are the organs.On their part, organs also have their functional units such as cells. All organs work together, and no organ can function without requiring the other. Body processes move from one organ to the other. For instance, In the digestive system, food has to pass from the mouth as the external organ and then move to the other internal organs like the stomach. This paper aims to look at the basics or the nervous system and the reproductive system by exploring their components.Keywords: Nervous System, Neuron, Reproductive System, Hormones

THE LIVING BODY2The Living BodyTask 1Question (3.1)(i)ReceptorReceptors are cells within the nervous system that are adapted for the detection of stimuli[ CITATION Moini2015 \l 1033 ]. A stimulus can be either internal changes like PH or external changes like a light mainly exist in five categories. The mechanoreceptors detect mechanical stimuli, i.e. touch. The photoreceptors detect light. Chemoreceptor detects chemicals,

THE LIVING BODY3i.e. salt in food. Thermoreceptor detects heat. The nociceptor detects pain. After the detection, these changes are transformed from normal changes to electrical impulses[CITATION jones2011neurological \l 1033 ]. (ii)Sensory neuronTheir function is to pick the message or the impulses generated by the receptor and transport it to the central nervous system (CNS)[CITATION jones2011neurological \l 1033 ]. What happens is that after detection of the stimulus by the receptor, the impulses excite the sensory neuron[CITATION finkel2014pharmacology \l 1033 ]. The sensory neuron the travels with the message to the interneuron within the (CNS).(iii)Integration centerThe integrating center functions as the place where all signals meet. Signals from different receptors come to the integration center, and some could be even holding information that that is responding to different forms of stimuli[CITATION watson2014human \l 1033 ]. The integration center’s output represents the integration of various bits of responses. For simple reflexes, the integration center occurs as a single synapse called a monosynaptic reflex[ CITATION Moini2015 \l 1033 ].(iv)Motor neuronThese neurons carry efferent impulses processed from integration center and takes them to the effector[CITATION plowman2013exercise \l 1033 ]. The information carried by the motor neuron is more like processed commands carrying specific instructions for the effector ordering it to change a particular activity[CITATION colville2015clinical \l 1033 ]. The path taken by a
