NERVOUS SYSTEM The human body’s activities are regulated by two systems – the nervous system and the endocrine system. Although both systems control body functions‚ their methods differ. The nervous system is the body’s information gatherer‚ storage center and control system. Its primary function is to collect information about the external conditions in relation to the body’s external state‚ to analyze this information‚ and to initiate appropriate responses to satisfy certain needs; the most

The action of lifting an arm can seem like a thoughtless movement‚ however‚ there is complex and intricate process that goes on within the human body to make that small movement happen. It involves bones‚ muscles‚ and nerves to complete this process‚ but it would not be able to start without a certain subconscious thought beforehand. Lateral abduction of the arm is defined as raising the humerus‚ radius‚ and ulna bones to ninety degrees‚ parallel to the ground‚ with the elbow extended‚ and wrist

Around the axon in small cylinder-like wrappings is different tissue called the myelin sheath. At the end of the axon is small gap called the synapse. The synapse is the bridge between nerve cells that transfers the information. The synapse is made of three parts: the presynaptic ending‚ where the neurotransmitters are‚ along with some other cell organelles; the postsynaptic ending is the part that receives what the presynaptic ending lets go and the postsynaptic ending can be another axon‚ a dendrite

Amplification occurs until bare nucleocapsids spill into the myoneural junction and enter motor and sensory axons.
