HBS EXAM 1 QUESTIONS WITH 100%
CORRECT ANSWERS
What is the basic structure and function of a neuron?
Neurons are the basic building blocks of the nervous system. These specialized cells are the
information-processing units of the brain responsible for receiving and transmitting information.
Each part of the neuron plays a role in the communication of information throughout the body.
How do the different types of neurons work together to send and receive signals?
One neuron sends a signal, sending positve ions imto the other neuron, which is known as action
potential. The neuron the releases neurotransmitters into the synapse, and connects to receptors
How and why does reaction time differ in reflex and voluntary actions?
Voluntary- message sent to brain
Invokuntary- reflex arc
How are electrical impulses created in the human body?
The have to be activated by stimuli such as light, sound, heat, pressure, or chemicals released by
other neurons.
How do neurons convey information using both electrical and chemical signals?
The electrical signal travels down the axon to the axon terminals where it tells the vesicles to
release the neurotansmitters into the synaptic cleft which travel to the receptors of receiving cell
which releases the second messengers
What factors impact our ability to react to a stimulus?
Things that directly influence our activity
How do errors in communication impact homeostasis in the human body?
Electrical impulse travels down the axon and reach the axon terminal alerting the vesicles to the
receptors of the receiving cell which releases the second messangers
, How can biomedical professionals help treat, cure and improve the quality of life of those
suffering from nervous system disorders
Can provide a plan, medications and surgeries for the patient.
Motor neuron
*Efferent Neuron - Moving toward a central organ or point
*Relays messages from the brain or spinal cord to the muscles and organs
* conduct impulse to a effector (muscle or gland)
Sensory neuron
*Afferent Neuron - Moving away from a central organ or point
*Relays messages from receptors to the brain or spinal cord
*conduct impulse to spinal cord
Interneuron
*Relays message from sensory neurone to motor neurone
*Make up the brain and spinal cord
*Interconnect the sensory neuron with appropriate motor neuron
Cell membrane
Protects cell body
Cell body
Holds cytoplasm and the nucleus
Nucleus
Holds all info needed for protein synthesis
Axon terminal
Carries nerve impulse towards the next nerve
Nodes of ranvier
