TMA2: DESCRIBE HOW NEURONS IN THE CENTRAL NERVOUS SYSTEM COMMUNICATE. INTRODUCTION. As we human being are biological being‚ we need to understand our biological make up‚ and we can only fully understand the different parts of our bodies by studying further. This essay aims to address research methods used to study and understand how we evolved. Our knowledge of the human body has grown and psychology itself has become an expanding field of knowledge‚ various research and studies have been

Neurogenic Shock Neurogenic shock is a type of shock that is caused by a spinal cord injury that affects important nerves in the nervous system. Injury to the nervous system causes the walls of blood vessels to relax‚ which increases the blood pressure. Neurogenic shock mainly affects the spinal cord. The spinal cord consists of nerves that carry incoming and outgoing messages between the brain and the rest of the body. Neurogenic shock occurs when a spinal cord injury happens‚ particularly involving

communication systems in the brain The Nervous System and the Endocrine System Nervous System: extensive network of nerve cells that carry messages in pulses of electrical and chemical energy throughout the body. This is the network that first comes to your rescue by accelerating you heart and tensing your muscles for action. Endocrine System: a slower acting communication network that sends a follow up message that supports and sustains that support the emergency response initiated by the nervous system

If the stimulation exceeds the cell’s threshold‚ a new impulse begins. 7. The autonomic nervous system regulates activities that are involuntary. 8. I don’t know. I’m really tired. Maybe. 9.
