   Feb 20, 2024 · The three main parts of the brain are the cerebrum, cerebellum, and brainstem. 1. Cerebrum. Location: The cerebellum occupies the upper part of the cranial cavity and is the largest part of the human brain. Functions: It’s responsible for higher brain functions, including thought, action, emotion, and interpretation of sensory data.

   The human body has a nervous system that enables us to sense and respond quickly to changes outside and inside the body. Examples of stimulus (e.g. increase in temperature) and response (e.g. sweating). The structures that make up the central nervous system (CNS) and peripheral nervous system (PNS). Receptors detect stimuli; they can be single ...

   Where does a neurone end?

   • The neurone ends in either a muscle or gland, which are effectors. The flow chart summarises how information flows from receptors to effectors in a coordination system. The diagram summarises how information flows from receptors to effectors in the nervous system. Neurones do not connect physically with one another.

   Which neurones carry electrical signals to the central nervous system?

   • Sensory neurones carry electrical signals - nerve impulses - towards the central nervous system (spinal cord and brain). The signal starts in a receptor which detects a change. Relay neurones carry nerve impulses within the central nervous system. Motor neurones carry nerve impulses away from the central nervous system.

   How is the nervous system broken down?

   • Nervous system breakdown (diagram) So nervous tissue, comprised of neurons and neuroglia, forms our nervous organs (e.g. the brain, nerves). These organs unite according to their common function, forming the evolutionary perfection that is our nervous system. The nervous system (NS) is structurally broken down into two divisions;

   How does the nervous system work?

   • The nervous system allows us to react to our surroundings and coordinate our behaviour. The conditions inside our body must be carefully controlled if the body is to function effectively. The conditions are controlled in two ways with chemical and nervous responses. receptor Organ, tissue or cell that detects a stimulus.

    Transmission of a signal between neurons is generally carried by a chemical called a neurotransmitter. Transmission of a signal within a neuron (from dendrite to axon terminal) is carried by a brief reversal of the resting membrane potential called an action potential.
