Central Nervous System

Explanation:

The Central Nervous System (CNS) comprises of the Brain and the Spinal cord. IT involves in assembling information from all over the body and harmonizes various roles and activity. The Brain plays a major central and integral role in the coordination of most bodily functions such as locomotion, speech, thoughts, memory etc.

Inputs of information as stimuli or signals are processed to the brain through the afferent neurons, the pathway these signals follows is the interneurons and the feedback response is relayed to the targeted areas via the efferent neurons.

The Central nervous system also consist of Non-neuronal cells such as they glia cells whose main function is to provide homeostatsis(maintaining the internal environment), formation of the myelin( lipid fats that surronds the axon of the nerve cells) and to provide support, protect and proffers firmness to the neurons in the Central Nervous System.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
