DSM - CNS

• imbalances to temperatures homeostasis, weight loss, a decrease in cognitive abilities, hallucinations and even death may all be caused by sleep deprivation
• which of the following structures is not part of the limbic system?

  caudate nucleus
• nearly all stimuli destined for cerebral cortex must first pass through the thalamus
• the most important part of the brain in terms of our immediate survival is the brainstem
• the ability to produce language is a function of Broca's, whereas the ability to understand language is a function of Wernicki's area
• what type of fiber carries information from the frontal lob of the right cerebral hemisphere to occipital lobe of the same cerebral hemisphere?

  association fibers
• the primary visual cortex is located in the occipital lobe
• which of the following areas of white matter is not located within the cerebral hemispheres?


  funiculi
• the deep grooves in the cerebrum are known as fissures
• what is not part of the cerebrum?

  brainstem
• which lobe is situated posteriorly in each cerebral hemisphere?

  occipital
• it is in the medulla oblongata that corticospinal tracts decussate, meaning that the motor fibers originating from the right cerebral cortex descend through the left side of the spinal cord, and vice versa
• the neurotransmitter orexin plats a role in the promotion of wakefulness
• the cerebellar cortex is extensively folded causing the white matter to resemble tree branches and thus is called the arbor vitae
• what functional brain system participates in memory, learning, emotion, and behavior?

  limbic system
• dreams occur during which stage of sleep?

  REM
• an elevated ridge of the surface of the cerebrum is known as a gyrus
• the central sulcus separates the parietal and frontal lobes
• during development of the nervous system, the telencephalon will become the cerebral hemispheres
• what provides a link between the nervous system and the endocrine system?


  hypothalamus
• the cerebellum functions in the planning and coordination of movement
• the two brain structures concerned directly with maintenance of homeostasis include certain nuclei in the brainstem and the hypothalamus
• cognition is best described as recognizing, processing, planning, and responding to stimuli
• which brain nucleus serves as the body's "master clock"?

  suprachiasmatic nucleus
• integrative functions are carried out by the central nervous system
• which of the following structures connects the brain to the spinal cord?

  brainstem
• what component of the diencephalon secretes the hormone melatonin?

  pineal gland
• our conscious processes, such as planning movement, interpreting incoming sensory stimuli, and complex higher functions, are all functions of the cerebral cortex (neocortex)
• the hypothalamus regulates homeostasis, the autonomic nervous system, the endocrine system, and the sleep / wake cycle
• what are the three primary brain vesicles that form from the neural tube?


  forebrain, midbrain, hindbrain
• bundles of white matter in the cerebrum are known as tracts
• All of the following are ascending tracts of the spinal white matter except corticospinal tracts
• the descending motor tracts that allow for reflexive movement fo the head and eyes are the tectospinal tracts
• which of the following actions is not a function of the spinal cord?

  interprets stimuli
• the innermost, delicate menix that follows the gyri and sulci of the brain is known as the pia mater
• which of the following should not cross the blood-brain barrier with ease?

  large, polar molecules
• cerebrospinal fluid (CSF) is formed by choroid plexus and reabsorbed through arachnoid granulations into dural sinuses
• the hole in the spinal cord through which CSF flows is the central canal
• somatic sensory neuron cell bodies are located in the posterior root ganglion
• the periosteal and meningeal layers of the dura mater are fused together in all regions except dural sinuses
