HBS Unit 2 Review Questions & Answers, 100% Accurate, verified. What part(s) of the brain are responsible for vision? - ✔✔-Occipital lobe What part(s) of the brain are responsible for muscle coordination? - ✔✔-Cerebellum and pons What part(s) of the brain are responsible for feelings like happiness and anger? - ✔✔-Frontal lobe and amygdala What part(s) of the brain are responsible for breathing? - ✔✔-Brain stem and medulla oblongata What part(s) of the brain are responsible for speech production? - ✔✔-Broca's area and motor cortex What part(s) of the brain are responsible for smell? - ✔✔-Sensory cortex What part(s) of the brain are responsible for long term memory? - ✔✔-Hippocampus, temporal lobe, and frontal lobe What part(s) of the brain are responsible for short term memory? - ✔✔-Prefrontal cortex and temporal lobe What part(s) of the brain are responsible for hearing? - ✔✔-Auditory cortex and midbrain What part(s) of the brain are responsible for blood pressure regulation? - ✔✔-Medulla oblongata What part(s) of the brain are responsible for "fight or flight response"? - ✔✔-Pituitary glands, pineal glands, and pons What part(s) of the brain are responsible for problem solving? - ✔✔-Frontal lobe What part(s) of the brain are responsible for pain, touch, and temperature? - ✔✔-Parietal lobe What are the three different types of neurons? - ✔✔-Motor neurons, sensory neurons, and interneurons What is the function of a motor neuron? - ✔✔-To send information away from the central nervous system to muscles or glands What is the function of a sensory neuron? - ✔✔-To send information from sensory receptors toward the central nervous system What is the function of an inter neuron? - ✔✔-To send information between sensory neurons and motor neurons What is an afferent neuron? - ✔✔-Sensory neuron What is an efferent neuron? - ✔✔-Motor neuron What is the function of the cell body part of a neuron? - ✔✔-The central cell body is the largest part of a neuron and contains the neuron's nucleus, associated cytoplasm, and other cell structures. The cell body produces proteins needed for the construction of other parts of the neuron What is the function of the axon part of a neuron? - ✔✔-Typically carry signals away from the cell body. They are long nerve processes that may branch out to convey signals to various areas What are the function of the dendrites of a neuron? - ✔✔-Typically carry signals toward the cell body. Dendrites are usually more numerous, shorter and more branched than axons. They have many synapses in order to receive signal messages from nearby neurons What is the function of the myelin sheath of a neuron? - ✔✔-The Myelin Sheath of a neuron consists of fat-containing cells that insulate the axon from electrical activity What is a neurotransmitter? - ✔✔-The brain chemicals that communicate information throughout our brain and body What is repolarization in the terms of an action potential? - ✔✔-The change in membrane potential that returns it to a negative value just after the depolarization phase of an action potential has changed the membrane potential to a positive value What is depolarization in terms of an action potential? - ✔✔-A positive-going change in a cell's membrane potential, making it more positive, or less negative, and thereby removing the polarity that arises from the accumulation of negative charges on the inner membrane and positive charges on the outer membrane of the cell What is resting potential? - ✔✔-The electrical potential of a neuron to its surroundings when not stimulated or involved in passage of an impulse What is a voluntary reflex? - ✔✔-A much slower reaction that goes through the brain What is an involuntary reflex? - ✔✔-A quicker reaction that does not require going through the brain What is the cause of Multiple sclerosis? - ✔✔-Destruction of the myelin sheath What is the cause of Alzheimer's? - ✔✔-Affects chemicals tha
