Assignment 3 Written Essay Questions 1. a) We are able to experience different types of sensations because our nervous system encodes messages. German physiologist Johannes Muller in his doctrine of specific nerve energies described a kind of code which is anatomical. In his doctrine‚ Muller explains that different sensory modalities exist because signals received by the sense organs stimulate different nerve pathways that lead to different areas of the brain. For example‚ when the ear

auditory nerve and is composed of three divisions‚ the external ear‚ the middle ear‚ and the inner ear. The greater part of which is enclosed within the temporal bone. The ear is looked upon as a miniature receiver‚ amplifier and signal-processing system. The structure of the outer ear catching sound waves as they move into the external auditory canal. The sound waves then hit the eardrum and the pressure of the air causes the drum to vibrate back and forth. When the eardrum vibrates its neighbour

Adrenal glands secrete the hormone known as cortisol‚ which is used in the regulation of blood pressure‚ heart activity‚ metabolism and the immune system. These glands also produce aldosterone‚ which regulates electrolytes and bodily fluids. Whenever you exercise or feel stressed‚ your adrenal glands kick into gear‚ producing various levels of adrenaline. When things go wrong with your adrenal glands

Endocrine Vs Nervous System The endocrine system acts with nervous system to coordinate the body’s activities. Both systems enable cells to communicate with others by using chemical messengers. The endocrine system uses chemical messengers called hormones that are transported by the circulatory system (blood). They act on target cells that may be anywhere in the body. The endocrine system is slower than the nervous system because hormones must travel through the circulatory system to reach their
