throughout the central (autonomic) nervous system and peripheral (somatic) nervous system where it binds to and stimulates cholinergic receptors‚ specifically muscarinic and nicotinic receptors (Mileson et al. 1998). The autonomic nervous system controls visceral functions in the body and ACh acts at muscarinic and nicotinic receptors present at effector organs such as heart‚ eyes‚ glands‚ respiratory and gastrointestinal systems. The somatic nervous system controls all voluntary functions of

1.An extensive network of specialized cells that carry information to and from all parts of the body is called the nervous system. 2.The basic cell that makes up the nervous system and which receives and sends messages within that system is called a neuron. 3.The long tube-like structure that carries the neural message to other cells on the neuron is the axon. 4.On a neuron‚ the branch-like structures that receive messages from other neurons are the dendrites. 5. The cell body of the neuron‚ responsible

Biopsychology Bio psychologists argue behaviour is the product of our genes and behaviour and experiences are caused by the activity in the nervous system. CENTRAL NERVOUS SYSTEM Made up of the BRAIN and SPINAL CORD. NEURONS Make connections between each neuron‚ sending nerve impulses across the synapse. These make up the nervous system and determine what we‚ think‚ feel‚ say and do. A Motor Neuron _______________ _______________ ____________ ____________ ____________ ____________

www.Axiobionics.com Columbus OH NeuroProsthetics NeuroProsthetics are devices that interact with and control the nervous system. They are designed to reproduce or substitute for neurological and physiological function that has been lost to injury or disease. Wearable electrical stimulation systems deliver impulses to peripheral nerves. They induce a variety of beneficial effects‚ including muscle building‚ relaxation of spastic muscle‚ improvement of blood circulation
