uncrossed (lower branch of CN7 and CN12 nerve). The nuclei receiving pyramidal tract input are the ones that mediate voluntary movements of the cranial musculature through cranial nerves V (the trigeminal nerve), VII (the facial nerve), IX, X, and XI (the glossopharyngeal, vagus, and accessory nerves), and XII (the hypoglossal nerve). 13. Describe in full detail the examination of the motor functions. Methods of motor function study A doctor carries out an examination in such a sequence. At first it is neces sary to exam the volume of active movements in the limbs, including Barre's test(upper and lower, the"Budda" posture, the examination should be start ed with big joints to small ones. The muscle strength of the limbs is estimated by five point score: 5 - normal, 0 - absence of the muscle strength when examination of passive movements in limbs is performed the doctor estimates the of the limbs, defines the presence of atrophy and fibrillar twitches.

the physiological and pathological reflexes described above. Remember that exploration were are pathological reflexes of the extension group physiological for children under one. After examination the character of paralyses on the basis of the revealed pathological symptoms the topical d agnosis established. 14. Describe in full detail the physiological reflexes – classification, how to elicit them, reflex arch. The levels of the spinal reflex arches locking -Biceps flexor ulnar(C5-C6 segments) -Brachioradialis carporadial(C5-C8 segments) -Extensor ulnar(C7-C8 segments) -Triceps Abdominal(T7-T12 segments) -Cremasteric(L1-L2 segments), -Quadriceps knee jerk) (L2/3-LA segments) -Plantar(L5-S1 segments) -Achilles(S1-S2 segments) - Anal wink(S3-S5 segments) Methods of the inborn (physiological) reflexes study To master the methods of the inborn reflexes study fulfill the reflexes study in the following sequence. The hammer strikes are performed with equal force. Pay attention if the below mentioned normal reaction is achieved. - Corneal reflex - carefully touch of the cornea above the iris(not above the pupil) with a soft paper stripe leads to lids closing. - Pharyngeal reflex - a touch of the posterior pharyngeal wall with a spat ula leads to swallowing or coughing movements occur. - Palatal reflex - touch the soft palate with a spatula leads to the soft palate elevation. -Mandibular(jaw) reflex - strike your index finger put on the patient's mandible with a hammer(mouth is half-open) leads to the mandible elevation. -flexor ulnar(Biceps) reflex - half-bended arms are placed on the pa tient's abdomen. Press the arm biceps muscle tendon with your left polle. Strike your pollex nail with a hammer. As a result, forearm flexion appears. - extensor ulnar(Triceps) reflex - a patient's arm is bent under an obtuse angle. Strike the arm triceps muscle tendon (2 cm above the ulnar process) with a hammer as a result forearm extension will appear.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
