Functions in planning, organizing, and coordinating motor movements and posture

Question

Functions in planning, organizing, and coordinating motor movements and posture Motor for speech in the left cerebral cortex in most people. Detects superficial pressure and light touch. Detect two distinct receptor fields by touching at two points on the skin. Long-lasting pain where sufferer feels helpless and hopeless and relies on drugs. A state of consciousness in which an individual H. Basal nuclei cannot be aroused and does not respond to stimuli. The nerve tract that innervate the head muscles. A painful sensation in a region of the body that is not the source of the pain stimulus. A map of the sensory and motor cortex of the cerebrum. When axons cross over from one side of the brain to the other, they are said to _____. A tract as associated with the pyramidal or direct pathway of motor control. The spinal tract that relays info concerning pain and temperature to the CNS. The brain waves characteristic of newborn infants. A. Coma B. Chronic pain C. Corticobulbar tract D. Merkel's disk E. Referred pain f. Trigeminal nerve G. Ependyma H. Basal nuclei I. Arbor vitae J. Homunculus K. Lateral spinothalamic tract L. Tectum M. Delta waves N. Broca area O. Limbic system P. Decussate Q. Meissner's corpuscle R. Olfactory nerve

Explanation / Answer

1. H is match for Q.1. Cerebral cortex interact with basal nuclei and cerebellum in planning , coordination and execution of movement. Basal nuclei can be stmulatory or inhibitory.

2. N is match of question 2. Broca area present in left hemisphere that fuction associated with language processing and speech production.

3. D is match for q.3. Merkel disk detect light touch and superficial pressure, located in epidermis and capsule around the nerve ending.

4. Q. is match for 4. Meissner's Corpuscle involve in two point discrimination means the ability to detect simultaneous stimulation at two point of the skin.

5. B is match for q.5. Chronic pain is when person suffers from pain in particular part of body for the long time. It is much worse than short term pain.

6. A is match for q.6. Coma is state of consiousness in which an individual can not aroused and doesn't respond to stimuli.

7. C is match for q.7. Corticobulbar tract is two neuron white matter motor pathway that innervate head muscle. Muscles of face, head and neck are controlled by thic tract.

8. E is match for q.8. The painful sensation in the region of body that is not the source of stimulas called referred pain. When internal organs are damaged or inflamed , refered pain sensed in skin most commanly. The sensation usually occur because both the area to which pain to occur and area where actual damage occur innervated by the neurons from same spinal segment.

9. J is the match for q.9. Homunculus is a map of sensory and mortor cortex of cerebrum. Mapping of our sense of touch onto the cortex give us a representation of the body named as homunculus.

10. P is the match of q.10. When exon cross one part of brain to another like chromosome crossing over , this term is called decussation where nerve fibre obliquely crosses one lateral part to another.

11. C is the match for 11.

12. K is the answer of Q.12. Lateral spinothelemic tract relays information concerning pain and the temperature to the CNS.

13. M is answer of q.13 . delta wave found in newborn infants EEG. It is high amplitude brain wave characterizing depth of sleep. Infants have shown to spend a great deal of time in slow wave sleep , thus have more delta wave activity. It is predominate wave form of infants.
