Which part of the brain is referred to as the central switchboard?

Which part of the brain is referred to as the central switchboard?

This area of the brain is further divided into three areas—the diencephalon, the cerebrum, and the cerebral cortex. The diencephalon, which lies below the cerebrum, includes the thalamus, hypothalamus, and epithalamus (Fig. 43-2). The thalamus is the major “relay station,” or “central switchboard,” for the CNS.

What is the information switchboard of the brain?

The thalamus is the brain’s sensory switchboard. It directs messages to the sensory areas in the cortex and transmits replies to the cerebellum and medulla.

Which part of the brain acts as the control center or switchboard?

The largest part of the brain, the cerebrum has two hemispheres (or halves). The cerebrum controls voluntary movement, speech, intelligence, memory, emotion, and sensory processing.

What carries messages to the central part of a neuron?

The dendrites carry messages toward the nerve cell body, or center of the neuron. The axon carries messages away from the cell body. The cell body contains the nucleus of the neuron.

What is the central switchboard of the central nervous system?

The midbrain is a short cylinder from which the stalks of the two cerebral hemispheres (forebrain) arise. It contains the cells of some cranial nerves, relay stations for the senses of sight and hearing, and centres for the coordination of movements. It appears to act as a central switchboard for the whole brain.

What is the switchboard of the nervous system?

The midbrain acts like a complex switchboard, allowing the brain to communicate with the rest of the nervous system.

How does the brain send messages to the body?

The brain is the body’s control centre: it sends messages to your body through a network of nerves called “the nervous system”, which controls your muscles, so that you can walk, run and move around. The nervous system extends through your body from your spinal cord, which runs from your brain down your backbone.

What is the prefrontal cortex?

The prefrontal cortex is a part of the brain located at the front of the frontal lobe. It is implicated in a variety of complex behaviors, including planning, and greatly contributes to personality development.

What is the center of your brain called?

The brainstem (middle of brain) connects the cerebrum with the spinal cord. The brainstem includes the midbrain, the pons and the medulla.

How do messages travel to and from the brain through the nervous system?

When neurons communicate, the neurotransmitters from one neuron are released, cross the synapse, and attach themselves to special molecules in the next neuron called receptors. Receptors receive and process the message, then send it on to the next neuron. 4. Eventually, the message reaches the brain.

How do messages travel to and from the brain?

When neurons communicate, the neurotransmitters from one neuron are released, cross the synapse, and attach themselves to special molecules in the next neuron called receptors. Receptors receive and process the message, then send it on to the next neuron. Eventually, the message reaches the brain.

What is the system that transmits messages between the central nervous system and all other parts of the body?

Peripheral Nervous System (PNS)
The Peripheral Nervous System (PNS) connects the CNS to other parts of the body, and is composed of nerves (bundles of neurons).
