B6 - The Brain and Mind - 6 Mark Question Practice A. Neurones are specialised cells transmitting nerve impulses. There are two types of neurones; Sensory cells‚ which send impulses from the receptor to the central processing centre and the motor neurones‚ transmit impulses from the brain and spinal cord to the effector cell that will respond to the stimulus. Impulses flow along thin tubes of cytoplasm. In the sensory neurones‚ the cell body is located in the middle and two tubes

Brain Function Table Component Definition Role in Learning and Development Neurons A neuron is a cell in the brain or another part of the nervous system that transmits information to other cells. Neuron cells are the information processing components of the brain responsible for receiving and transmitting information. Each part of the neuron plays a role in the communication of information throughout the body. Neurotransmitters A neurotransmitter is a chemical substance through which

1.2: Using one or more examples‚ explain effects of neurotransmission on human behavior: Our nervous systems consist of between 10 to 100 billion neurons; each of which making 13 trillion connections with each other through electrochemical messages that allow people to respond to stimuli‚ from the environment or from internal changes in a person’s body. The neurons send these electrochemical messages through neurotransmission. Electrical impulses traveling down the axon (body) of a neuron‚ instigates

1. Brainstem- It begins where the spinal cord swells after entering the skull. It regulates all automatic survival roles‚ such as breathing and heartbeats. 2. Thalamus- The thalamus is the uppermost part of the brainstem. It directs information to the sensory cortex and provides feedback to the cerebellum and medulla. 3. Medulla- The foundation of the brainstem. It manages heartbeat and breathing. 4. Reticular formation- The nerve region travelling through the brainstem and thalamus. The network

Guillain-Barre syndrome (GBS) is an autoimmune disorder of rapid-onset muscle weakness as a result of damage to the peripheral nervous system. The peripheral nervous system is the portion of the nervous system that is outside the brain and spinal cord. Autoimmune means an illness that occurs when the body tissues are attacked by its own immune system. In this case they begin attacking nerve cells which communicate with muscles. They attack the myelin sheaths surrounding the axons of the nerve cells

As I was waI stopped to take a breather as I was done finishing my last lap out of the 4 miles. I had called my mom to pick me up and ten minutes ago‚ but she was not here yet‚ I just assumed she was just running a little bit late. I can tell you standing outside in the flaming fiery sun‚ covered in sweat with no water bottle in hand is no fun. As I was waiting beads of sweat‚ thermoregulatory sweating‚ started appearing on my skin. The two types of sweating are eccrine glands‚ armpits‚ and apocrine

Tinnitus referred as ears ringing‚ in humans‚ can be caused by a variety of factors; such as high-level sound exposure‚ ototoxic drugs‚ and hearing loss. It is basically the self perception of sound in the absence of acoustic stimulation. the sound waves hit the outer ear and converge into the ear drum. The vibrations at ear drum are transferred into the inner rear through the middle ear. Once the sound waves reach inner ear‚ they travel through the cochlea towards the organ of corti. Further the

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
