This is stored in the axon. An electrical impulse starts in the neuron. The charge is sent down the axon and this is how it starts. A neuron has three basic parts: the body or soma‚ the axon and the dendrites. The Cell body is the center for sending and receiving impulses. The axon is a tube like extension of a neuron. Axons extended can be up to 3 feet long (psychology textbook). Nerves are actually bundles of axons. Axon receives the impulse from the cell body and passes it on to the next

The senses transmit sensory information’s‚ in the form of electrochemical impulses‚ to the brain. Different forms of energy stimulate the sensory receptors – the nerve endings and cells that detect sensory information. The sensory receptors then initiate neural impulses. Sensation occurs when the neural impulses arrive at the cerebral cortex. Neural impulses that begin in the optic nerve are sent to the visual areas of the cerebral cortex‚ and we see objects. Each person’s unique perception results

ASSIGNMENT BRIEF Scenario You are a ‘gifted and talented’ athlete who is taking part in some training and your coach has insisted that you understand more about HOW your body works during exercise to maximise your training and ultimately your performance. You will participate in some practical activities and look at readings to interpret what the body systems do in response to becoming active. How we physiologically change from being at rest to being active. Criteria reference To

Neurons: The Basic Elements of Behavior Neurons‚ or otherwise called nerve cells‚ are the basic elements of our nervous systems. We have as many as one trillion nerve cells throughout our bodies. These cells are responsible for controlling our behavior. So what is a neuron? “A neuron is a nerve cell that is the basic building block of the nervous system. Neurons are similar to other cells in the human body in a number of ways‚ but there is one key difference between neurons and other cells

It is important to know the structures and anatomy that make up the eyes to gain a better understanding of how light and images are processed to become sight. ANATOMY The lacrimal gland‚ or tear duct‚ produces tears when stimulated by the facial nerve. The delicate‚ transparent mucous membrane that covers the inside of the eyelids and the anterior surface of the eye is the conjunctiva. The sclera is the white‚ tough‚ fibrous connective tissue that makes up the whites of the eyes. The cornea is the
