Nervous Tissue + Brain Terms in this set (33)The right hemisphere is responsible for visual, emotional and artistic awareness, whereas the left hemisphere is responsible for language and calculation Which of the following distinguishes the right and left cerebral hemispheres form each other? It controls involuntary functions of the respiratory, digestive, and circulatory systems Which of the following is true of the medulla oblongata? Capillary walls Which of the following structures in the brain forms part of the blood-brain barrier that prevents harmful substances from entering brain tissue? Controlling reflexes. All of the following are functions of the brain except Meningeal and endosteal. The cranial dura mater is composed of two layers, which are the Posterior, inferior The cerebellum is located _____ to the brain stem and _____ to the occipital lobe of the cerebrum. Its hemispheres are symmetrical in function. If you were explaining the cerebrum to a friend who doesn't understand its structure or function, which of the following would not be part of your explanation? In the diencephalon, the interventricular foramen connects the lateral ventricles and the third ventricle. Which of the following accurately describes how particular ventricles are connected to each other? The internal carotid and vertebral arteries supply blood to the brain, whereas the dural venous sinuses and internal jugular vein drain the blood from the brain. Which of the following is an accurate comparison of the arteries and veins in the brain? Motor signals are transmitted mainly from the anterior cortex, whereas sensory signals are received and processed in the posterior regions of the cortex. Which of the following accurately identifies how information is processed in the cerebral cortex? Soma, many dendrites, and one axon.Soma, many dendrites, and one axon. A typical neuron consists of a(n) Negative, positive The resting neuron has a net _____ charge inside the cell and a net _____ charge outside it. Bones. Neurotransmitters are chemicals released at synapses that regulate the activity of all of the following except The adrenal medulla. Acetylcholine is a widespread neurotransmitter that is found in all of the following except In the adrenal glands Where are norepinephrine and epinephrine produced? Their structures are composed of neurons and neuroglia. Which of the following is a similarity between the central nervous system and the peripheral nervous system? Unipolar neurons are sensory neurons in which the axon splits into two branches that attach to the cell body. If one of your classmates asked you to explain the different types of neurons that can be classified by structure, which of the following would you include in your explanation? Oligodendrocytes have processes that reach out to multiple axon segments, whereas the entire Schwann cell surrounds just one axon segment. How do Schwann cells differ from oligodendrocytes? Prior to the process, the neuron is polarized; as the signal passes along the axon, the membrane depolarizes and repolarizes again, passing positive charges in and then back out. How would you explain the charge changes that occur in a neuron during the messaging process? Excitatory neurotransmitters encourage the transmission of an action potential, whereas inhibitory neurotransmitters inhibit transmission. Which of the following best explains how neurotransmitters affect an action potential? dendrites A neuron receives signals at its: Schwann Cells The cells that create a myelin sheath around peripheral nerve axons are called Polarized In resting state, the plasma membrane of a neuron is: electrically and chemically Signals are passed through the nervous system ___________ and ____________. The wave of depolarization that is propagated down an axon is known as the ___________ ___________. action potential false True or False: At a neuromuscular junction, acetylcholine has inhibitory effects. 1. Dendrites A signal moves through the parts of a single neuron in what order? More quickly than A myelinated axon transmits a signal ___________ a non-myelinated axon. C. The net charge inside the cell is negative When a neuron is not transmitting a signal, which of the following is
true? microglia Which type of cells phagocytize debris in the central nervous system? pia mater The innermost layer of the meninges of the spinal cord is the:
A. Gray matter passes information up and down the spinal cord. All of the following are true about gray and white matter in the spinal cord, EXCEPT: sensory, into; motor, out of Dorsal roots carry _______ signal _______ the spinal cord, while ventral roots carry __________ signals ________ the spinal cord.
