Nervous System

What is the function of nerve impulses in the nervous system?

• Transmit electrical signals between neurons

• Regulate blood pressure

• Produce hormones for growth

• Generate heat in the body

Which part of the nervous system consists of the brain and spinal cord?

• Peripheral nervous system

• Autonomic nervous system

• Somatic nervous system

• Central nervous system

What is the role of the peripheral nervous system?

• Regulates the endocrine system

• Manages the digestive system

• Controls the brain functions

• Connects the central nervous system to the limbs and organs, transmitting sensory information and motor commands.

Name a common neurotransmitter involved in mood regulation.

• Dopamine

• Serotonin

• Acetylcholine

• GABA

Describe how nerve impulses are transmitted along a neuron.

• Nerve impulses are transmitted along a neuron through action potential and neurotransmitter release.

• Nerve impulses are transmitted along a neuron through photosynthesis

• Nerve impulses are transmitted along a neuron through gravitational pull

• Nerve impulses are transmitted along a neuron through osmosis

What are the main functions of the central nervous system?

• Filtering blood, producing hormones, storing memories

• Processing sensory information, coordinating motor functions, regulating homeostasis, controlling behavior and emotions

• Digesting food, regulating body temperature, controlling muscle movement

• Transporting oxygen, regulating blood sugar, fighting infections

How do neurotransmitters facilitate communication between neurons?

• Neurotransmitters facilitate communication between neurons by physically connecting neurons together.

• Neurotransmitters facilitate communication between neurons by altering the DNA of the neurons.

• Neurotransmitters facilitate communication between neurons by transmitting signals across the synapse and binding to receptors on the postsynaptic neuron.

• Neurotransmitters facilitate communication between neurons by emitting light signals.

What are the two main types of nerve fibers in the peripheral nervous system?

• Visual fibers and auditory fibers

• Tactile fibers and olfactory fibers

• Sensory (afferent) fibers and motor (efferent) fibers

• Parasympathetic fibers and sympathetic fibers

Explain the process of synaptic transmission in the nervous system.

• Synaptic transmission involves the release of hormones instead of neurotransmitters.

• The process of synaptic transmission does not involve binding to receptors.

• Synaptic transmission occurs through direct electrical connections between neurons.

• The process of synaptic transmission involves neurotransmitter release, diffusion across the synaptic cleft, binding to receptors, and generation of postsynaptic potentials.

What happens when there is a disruption in neurotransmitter levels in the brain?

• Increased cognitive abilities

• No impact on mental health

• Neurological and psychiatric disorders can occur.

• The brain functions normally
