Understanding Control and Coordination

What are the main functions of the nervous system?

• Vision enhancement, sound amplification, and taste modification.

• Respiratory control, digestion, and blood circulation.

• Emotional regulation, memory storage, and hormone production.

• The main functions of the nervous system are sensory input, information processing, and motor output.

Describe the role of neurons in the nervous system.

• Neurons primarily store genetic information.

• Neurons are responsible for producing hormones in the body.

• Neurons transmit signals in the nervous system, facilitating communication between the brain, spinal cord, and the rest of the body.

• Neurons act as the main source of energy for the body.

What is a synapse and how does it function?

• A synapse is a connection point between neurons that facilitates communication through neurotransmitters.

• A synapse is a chemical that causes pain in the body.

• A synapse is a type of muscle tissue that contracts to move the body.

• A synapse is a type of blood cell that fights infections.

Explain the difference between sensory and motor neurons.

• Sensory neurons only function in the spinal cord; motor neurons only function in the brain.

• Sensory neurons carry information to the brain; motor neurons carry information from the brain to the body.

• Sensory neurons send signals from the body to the brain; motor neurons send signals to the brain.

• Sensory neurons are responsible for muscle movement; motor neurons are responsible for sensory perception.

How do neurotransmitters affect communication between neurons?

• Neurotransmitters are responsible for producing hormones.

• Neurotransmitters facilitate communication between neurons by transmitting signals across synapses.

• Neurotransmitters block signals between neurons.

• Neurotransmitters only affect muscle cells, not neurons.
