The most basic unit of the entire nervous system is the ______.
dendrite
neuron
brain
spinal cord
Which nervous system controls the activity of the structures inside your body, such as your heart or your endocrine glands?
the autonomic nervous system
the somatic nervous system
the central nervous system
the peripheral nervous system
Which of the following is most accurate?
The central nervous system includes the nerves through which the central nervous system interacts with the rest of the body.
The peripheral nervous system includes the brain and the spinal cord.
Afferent or sensory nerves carry information to the central nervous system from sensory neurons and regulate glandular secretion.
Efferent or motor nerves extend out from the central nervous system to the organs.
Communication among the neurons requires two main activities: electrical signal which are generated by _____ and chemical signals which are generated by _____.
resting potentials; neurotransmitters
neurotransmitters; action potentials
neurotranmitters; depolarization
action potentials; neurotransmitters
How are hormones different from neurotransmitters?
Hormones are chemical messengers.
Hormones are carried in the bloodstream.
Hormones are not regulated by the brain.
Hormones are by-products of neurotransmitters.
Regarding the electrical activity of neurons, which of the following is INCORRECT?
Neurons are integrators: they can have a vast number of different inputs, but they produce just a single output signal, which they transmit to their targets.
There is a small voltage difference between the inside and the outside of the neuron in its reading state known as the action potential.
The inputs to neurons are tiny amounts of chemical neurotransmitters.
In the steady state neuron, there is an active pumping of ions across the neuronal membrane.
Neurotransmitters and thus the brain function can be disrupted by _____.
antagonists
agonists
synapsis
Both antagonists and agonists
Long-term potentiation and long-term depression are processes demonstrating that _______.
experience can modify a neuron's responses
experience can modify a person's potential
experience can modify a person's mental health
All choices listed
Which of the following is NOT true of the human brain?
The cerebellum plays a key role in making movement smooth and efficient and lies at the back of the brain
The motor and sensory systems do not interact
The spinal cord, made up of both axons and ganglia, provides us with essential reflexes
The brain in comprised of two halves - or hemispheres
The main functions of the medulla are to _______.
regulate heart rate, blood pressure and respiration
regulate heart rate, blood pressure and respiration by connecting these impulses to the pons
send out motor impulses to the muscles once the thalamus sends the message to the Medulla
connect the hindbrain with the midbrain
