Across
- 1. Posterior part of the Proscencephalon (forebrain) containing the epithalamus, thalamus, metathalamus, hypothalamus, and the subthalamus
- 5. nervous system spends energy and prepares for fight or flight. In doing so constricts blood vessels, induces perspiration, dilates pupils, accelerates heart rate
- 7. Artery supplies most of the caudal third of the spinal cord. It is formed at the lower thoracic and upper lumbar level.
- 8. arteries arise in the circle of willis and are major arteries that supply external brain structures
- 10. is the site of interconnection between blood vessels. Also provides a system of revascularization in the brain collateral circulation in the case of vascular insufficiency.
- 11. tract regulates muscle tone for limb extension and posture in support of body against gravity. (sitting upright)
- 12. arteries arise in the circle of willis and are small arteries that penetrate the ventral surface of the brain to supply the internal and subcortical structures
- 15. The Midbrain connects the hindbrain and the forebrain
- 17. Nerves in the PNS have 12 pairs
- 21. nervous system conserves energy; dominant during relaxation or sleep; lowers heart rate, decreases body metabolism, constricts pupils
- 22. Cerebral Artery curves along the inferior brain surface to supply the temporal lobe, hippocampus, portions of the occipital lobe including the primary visual cortex.
- 25. mater is the outermost layer of the Meninges, attached to the surface of the skull; thickest and toughest layer; provides the most protection.
- 27. nervous system is an involuntary self-monitoring system regulated by the hypothalamus
- 29. the top of the horizontal plane and the back of the vertical plane
- 30. principle states that all primary sensory and motor regions in the cerebrum are connected through association and commissural fibers.
- 31. tract regulates neck and body twisting in response to visual and auditory stimuli (startle reflex – turn to look at something loud)
- 33. is a slowness of movement, including talking, walking or any voluntary movement.
- 35. fibers connect the two hemispheres of the brain.
- 39. roots contain efferent fibers and innervate skeletal muscle
- 40. cerebral artery damage results in contralateral hemiplegia, Impaired sensory functions of touch, tactile agnosia, reduced pain and temperature, aphasia, constructional deficits, homonymous hemianopsia, alexia and agraphia
- 41. Axonal fibers carry sensory impulses towards the CNS
Down
- 2. clinical symptoms present on the opposite side of the body to the lesion site
- 3. Carotid divides into the anterior cerebral and middle cerebral arteries
- 4. protects the central nervous system and consists of three layers
- 6. area of the brain that receive dual blood supply from large arteries.
- 9. Most anterior part of the Proscencephalon (forebrain) consisting mainly of the cerebral hemispheres
- 13. Sinus System is composed of Veins and sinuses collect deoxygenated blood and transport it back to the heart and lungs for reoxygenation.
- 14. spinal artery blood flow interruption results in hemiplegia and pain and temperature hemisensory loss (one side sensory loss).
- 16. Axonal fibers carry the commands away from the CNS
- 18. membrane is a thin membrane between the dura mater and pia mater in the Meninges
- 19. mater is a thin membrane attached to the surface of the brain in the Meninges that follows the contours of the sulci and gyri and surrounds blood vessels.
- 20. tract projects vestibular impulses to the spinal LMNs. Regulates extensor muscle tone to control the reflexive adjustments of the body and limbs and to keep the head stable.
- 23. system lifeblood of the nervous system; it provides oxygen and other nutrients to neural structures and removes waste from them. It is a major locus of abnormalities for motor speech disorders.
- 24. Hindbrain that develops into the metencephalon (pons and cerebellum) and mylencephalon (medulla oblongata)
- 26. fibers connect areas within the same hemisphere of the brain.
- 28. the front of the horizontal plane and bottom of the vertical plane
- 32. the back of the horizontal plane and the bottom of the vertical plane
- 34. clinical symptoms present on the same side of the body to the lesion site
- 36. is a sudden and momentary contraction of muscle groups
- 37. cerebral artery is responsible for supplying surfaces of the prefrontal, frontal, and parietal lobes.
- 38. Nerves in the PNS have 31 pairs in the
