There are three major brain divisions. They are the cerebrum‚ the brainstem‚ and the cerebellum. The cerebrum contains 40% of the weight of the brain and is founded in the superior part of the brain. This portion of the brain has many functions and lobes which perform certain functions. The frontal lobe is involved with “activating and controlling both fine and complex motor activities.” This involves speech. It is also involved with the executive functions‚ such as reasoning and rationalizing‚ among

The Nervous System The nervous system is the most complex part of the body‚ as they govern our thoughts‚ feelings‚ and bodily functions. It is an important factor in science because it can lead to new discoveries for cures or diseases. The studies of the nervous system helped lower death rates from heart disease‚ stroke‚ accidents‚ etc. The nervous system is a network of neurons (nerve cells) that that sends information to the brain to be analyzed. Neurons live both in and outside the central nervous

skeleton is often described as a solid‚ moveable framework that supports the body. Bone is a strong and rigid form of connective tissue. It also works as levers and anchor plates to allow movement to take place. Bones also work for alternative body systems for example the blood cells develop in their fatty inner tissue (red marrow). The body draws from mineral stores in bones during crucial times of shortage‚ for instance when calcium is needed for healthy nerve functioning. The skeletons key components

1] Describe the two branches of the ANS – transmitters‚ transmitter synthesis‚ outflow and major effects of each. The two branches of the Autonomic Nervous System are the sympathetic division and the parasympathetic division. The main process of the sympathetic division is to stimulate the fight-or-flight response in the body‚ which means it is in charge of stimulates actions. In the sympathetic system‚ epinephrine and norepinephrine are the main neurotransmitter. In the sympathetic system‚ there

There are many different functions of body fluids such as transporting nutrients‚ waste and gases‚ transforming food into energy and generate electrical activity to power body functions. Physiologic Fluid Compartments The major fluid compartments in the body are intracellular and extracellular fluid. Both compartments consist of oxygen‚ dissolved nutrients‚ carbon dioxide‚

Nervous System Functions of the Nervous System 1. Detect changes and feel sensations 2. Initiate responses to changes 3. Organize and store information Divisions 1. Central Nervous System – brain and spinal cord 2. Peripheral Nervous System – cranial nerves and spinal nerves (relays info to/from the CNS) - Autonomic Nervous System Nerve Tissue – neurons (nerve fibers) and specialized cells (Schwann‚ neuroglia) 1.

In any nervous system‚ there are 4 main components: (1) sensors: gather information from the external environment (sense organs) (2) conductors: carry information from sensors to modulators or from modulators to effectors (nerves)
