Fichas del conjunto (30)
- 1Name the components of the brain stem.Medulla oblongata, pons, midbrain.
- 2Name the components of the diencephalon.Hypothalamus, thalamus, epithalamus (with pineal gland)
- 3The brainstem is located between the __________ and the ________.Spinal cord, diencephalon.
- 4What part of the diencephalon transmits most sensory impulses from the spinal cord and brainstem to the cortex, and motor impulses from the cerebellum to the cerebral cortex?Thalamus.
- 5What part of the diencephalon is the major regulator of homeostasis and produces hormones?Hypothalamus.
- 6What part of the diencephalon contains the pineal gland and regulates melatonin?Epithalamus.
- 7What part of the brainstem contains four pairs of cranial nerves and regulates breathing?The pons.
- 8What part of the brainstem contains five pairs of cranial nerves and contains the cardiovascular center, respiratory center, vomiting center, and regulation center?The medulla oblongata.
- 9What part of the brainstem regulates reflexes in response to visual stimuli?The midbrain.
- 10Name the three protective coverings of the brain.1. Cranium (skull)
2. Cranial meninges (dura mater, arachnoid mater, pia mater)
3. Cerebrospinal fluid - 11What is responsible for draining venous blood from the brain and delivering it to the internal jugular veins?Dural venous sinuses.
- 12Extensions of the dura mater separate parts of the brain. What separates the two hemispheres of the cerebrum?Falx cerebri.
- 13Extensions of the dura mater separate parts of the brain. What separates the two hemispheres of the cerebellum?Falx cerebelli.
- 14Extensions of the dura mater separate parts of the brain. What separates the cerebrum from the cerebellum?Tentorium cerebelli.
- 15What is an epidural hematoma?Bleeding between the skull and the outer meninge (dura mater) that results after a severe injury to the skull.
- 16What is a subdural hematoma?Bleeding between the inner layer of the dura mater and the arachnoid mater, usually caused by the tearing of veins.
- 17What is a subarachnoid hemorrhage?Blood mixes with the cerebrospinal fluid. Caused by congenital aneurisms that rupture.
- 18What is the main source of ATP for neurons?Glucose via oxygen-dependent reactions.
- 19Is glucose stored in the brain?No.
- 20Deprivation of oxygen for how long causes permanent injury in the brain?Four minutes.
- 21What is CPP and how is it calculated?Cerebral perfusion pressure. The pressure gradient between mean arterial pressure and intracranial pressure (CPP = MAP - ICP)
- 22The blood-brain barrier is composed of tight junctions sealed together with what type of cells?Endothelial.
- 23How much cerebrospinal fluid does an adult normally have?80 - 150 mL.
- 24Ventricles are cavities within the brain that contain what? How many are there?Cerebrospinal fluid. Four total.
- 25What are the locations of the ventricles in the brain?1 & 2, one in each hemisphere of the cerebrum.
3, narrow cavity between the halves of the thalamus.
4, between brain stem and cerebellum. - 26The fluid formed from the blood plasma secreted by ependymal cells that cover the choroid plexuses of the ventricles is known as?Cerebrospinal fluid!
- 27The ventricle space between the third and fourth ventricle is known as what?The cerebral aqueduct.
- 28How is cerebrospinal fluid reabsorbed into the brain?Through the arachnoid villi.
- 29What is hydrocephalus?When the cerebrospinal fluid cannot properly drain.
- 30What is meningitis?Infection of the meninges (and the CSF).
