  2. Cruciate ligament - Wikipedia

    en.wikipedia.org/wiki/Cruciate_ligament

    The ability to move the tibia forward (cranially) with respect to a fixed femur is a positive cranial drawer sign indicative of a rupture (it will look like a drawer being opened). [ 9 ] Another method used to diagnose a rupture is the tibial compression test, in which a veterinarian will stabilize the femur with one hand and flex the ankle ...

  3. Posterolateral corner injuries - Wikipedia

    en.wikipedia.org/wiki/Posterolateral_Corner_Injuries

    If the rotation decreases compared to 30°, then an isolated PLC injury has occurred. [7] [8] Beware of a possible medial knee injury in the face of a positive dial test. Posterolateral Drawer Test - The posterolateral drawer test is similar to the commonly known posterior drawer test for PCL stability. Have the patient lie on their back with ...

    A major function: controls muscles for voice and resonance and the soft palate. Symptoms of damage: dysphagia (swallowing problems), velopharyngeal insufficiency. This nerve is involved (together with nerve IX) in the pharyngeal reflex or gag reflex. XI Accessory. Sometimes: cranial accessory, spinal accessory. Mainly motor Cranial and Spinal Roots

  5. Posterior cruciate ligament injury - Wikipedia

    en.wikipedia.org/wiki/Posterior_cruciate...

    The PCL is located within the knee joint where it stabilizes the articulating bones, particularly the femur and the tibia, during movement.It originates from the lateral edge of the medial femoral condyle and the roof of the intercondyle notch [5] then stretches, at a posterior and lateral angle, toward the posterior of the tibia just below its articular surface.

  6. Drawer test - Wikipedia

    en.wikipedia.org/wiki/Drawer_test

    An increased amount of anterior tibial translation compared with the opposite limb or lack of a firm end-point may indicate either a sprain of the anteromedial bundle or complete tear of the ACL. [2] If the tibia pulls forward or backward more than normal, the test is considered positive.

  7. Tibial nerve - Wikipedia

    en.wikipedia.org/wiki/Tibial_nerve

    The tibial nerve is the larger terminal branch of the sciatic nerve with root values of L4, L5, S1, S2, and S3. It lies superficial (or posterior) to the popliteal vessels, extending from the superior angle to the inferior angle of the popliteal fossa, crossing the popliteal vessels from lateral to medial side.

  8. Nerve injury - Wikipedia

    en.wikipedia.org/wiki/Nerve_injury

    Nerve growth factor (NGF) typically has a low level of expression in nerves that are healthy and not growing or developing, but in response to nerve injury NGF expression increases in Schwann cells. This is a mechanism to increase growth and proliferation of Schwann cells at the distal stump in order to prepare for reception of the regenerating ...

  9. Lower motor neuron - Wikipedia

    en.wikipedia.org/wiki/Lower_motor_neuron

    [2] [3] Cranial nerve lower motor neurons also control some voluntary movements of the eyes, face and tongue, and contribute to chewing, swallowing and vocalization. [4] Damage to the lower motor neurons can lead to flaccid paralysis, absent deep tendon reflexes and muscle atrophy.
