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

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

brain has many jobs. It controls our spinal cord‚ our central nervous system and our nervous system. The spinal cord carries messages to the brain and also to the nerve cells that carry messages from the brain. Your body senses everything. Like something smashing your toe. You react to it. It all sends itself to the brain and it reacts. The cerebrum‚ controls thinking. The nerve cells carry information from all central nervous system. Like certain areas‚ such as the 5 senses.

term Homeostasis to describe the body’s ability to maintain a constant stable internal environment despite the changes to the external surrounding1‚2. The body has a range of receptors these are used to constantly monitor the body’s internal conditions to keep them in physiological limits. To achieve this‚ every organ works together and thus the body works together as a whole. This requires body to communicate with the organs‚ this is established through two very highly specialized systems; nervous

Homeostasis‚ also spelled homoeostasis (from Greek: ὅμοιος‚ "hómoios"‚ "similar")‚ is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant. Examples of homeostasis include the regulation of temperature and the balance between acidity and alkalinity (pH). It is a process that maintains the stability of the human body’s internal environment in response to changes in external conditions. The concept was described by Claude Bernard

Autonomic Nervous System * The somatic nervous system consists of nerves that provide VOLUNTARY control over skeletal muscles * The autonomic nervous system exerts INVOLUNTARY control over the contraction of smooth muscle‚ cardiac muscle‚ and glandular activity. * Basic function of the Sympathetic VS Parasympathetic Systems * Sympathetic system= “fight of flight” * Parasympathetic system= “rest and digest” * Both autonomic branches are required for body homeostasis

Homeostasis A condition in which the internal environment of the body remains relatively constant despite changes in the external environment. Examples would be the maintenance of body temperature and levels of glucose in the blood Homeostatic mechanisms are designed to reestablish homeostasis when there is an imbalance.

In most animals the nervous system consists of two parts‚ central and peripheral. The central nervous system of vertebrates (such as humans) contains
