Anatomy Quiz 2 NWHSU
| Question | Answer |
|---|---|
| Define a Nerve | A group of neuron fibers in the PNS |
| The Tibial Nerve Contains fibers from these most of its course through the thigh | L4-S3 |
| Considering that muscle volume remains constant, What can one say when COMPARING range and strength of contraction of an Unattached (Free) muscle? | Inverse relationship. Range depends on length of fascicles and strength depends on cross sectional area of fascicles. |
| Give components which form the medial wall of the inguinal canal. | conjoined tendon, rectus sheath |
| Define the Deep inguinal ring | opening in transversalis fascia |
| cutaneous branch of tibial nerve which supplies skin of posterior calf | sural nerve |
| in reference to the nervous system define a nucleus | a group of neuron cell bodies in the CNS |
| Specifically what forms the conjoined tendon | aponeurosis of transversus abdominus muscle and aponeurosis of internal oblique muscle |
| A patient presents a sprained ankle caused by excessive eversion. Give specific ligamentous damage. | deltoid ligament |
| portion of the spermatic cord derived from the internal oblique | cremaster cord |
| name the cutaneous branches of the femoral nerve (Do not give articular) | medial and intermediate cutaneous nerves- saphenous nerves |
| In detail how does the great saphenous vein become a tributary to the deep veins? Include vein it drains into and how it gains access | It arises from dorsal digitals, dorsal metatarsals and dorsal venous arch and travels up medial leg to the saphenous hiatus which is a gap in the fascia lata. It then is a tributary to the femoral vein |
| The only muscular clinical sign a patient presents is involuntary inversion of the foot and foot drop. This would indicate injury specifically to the ______ nerve. | common fibular nerve |
| a ligament deep to the dorsal sacroiliac ligament, located in teh deep groove between the sacrum and ilium | interosseous sacroiliac ligament |
| A patient presents a sprained ankle caused by excessive inversion. Give specific ligamentous damage. | anterior talofibular ligament |
| Name the ligaments that run from the tibia to the lateral malleolus | anterior tibiofibular ligament, posterior tibiofibular ligament |
| apart from muscular paralysis, injury to this specific nere would present anesthesia of the skin in the small areas (Web) between the 1st and 2nd toes only. | deep fibular nerve |
| Use letter classification... motor fibers have a ganglion intermediate and Specifically innerate____. | GVE, smooth m. cardiac m. glands |
| The tibial nerve contains fibers from these specific spinal cord segments | L4-S3 |
| A patient presents flattening of the medial longitudinal arch on the plantar surface of the foot. Give specific ligamentous damage. (Proper names only) | plantar calcaneanavicular |
| Define the superficial inguinal ring | opening in aponeurosis of external oblique |
| What structure(S) anteriorly contribute(s) to the rectus sheath above the level of the anterior superior iliac spine? | aponeuroses of internal oblique, external oblique |
| Name 2 important ligaments with attachments to the ischium and sacrum | sacrotuberous ligament, sacrospinous ligament |
| specific nerve from which the lateral sural cutaneous nerve is a direct branch | common fibular |
| Assuming the sciatic nerve has been severed, would any cutaneous areas below the knee still have sensation? If so, specifically where and why? | Yes, Medial side of foot because of saphenous nerve |
| Component of the anterior abdominal wall from which the cremaster is derived | internal oblique muscle |
| specifically what forms the anterior wall of the inguinal canal | aponeurosis of external oblique muscle |
| nerve that traverses the adductor canal to provide cutaneous innervation to the medial side of leg, ankle, and foot to great toe | saphenous nerve |
| name the cutaneous branches of the femoral nerve. Do not give articular | saphenous nerve |
| muscle in which the common peroneal nerve divides into its terminal branches | fibularis longus |
| the obturator nerve carries fibers from these spinal segments | L2-4 |
| The sciatic nerve descends posterior to the _____ muscle during most of its course through the thigh | adductor magnus |
| specific vessel supplying skin of lower part of the abdomen and external genitalia | superficial external pudendal artery |
| Beginning with the popliteal artery, make a flow chart showing the course a drop of blood would mainly take to reach the lateral compartment muscles of the leg. | popliteal artery-->posterior tibial--> peroneal artery |
| Portion of the spermatic cord derived from the aponeurosis of the external oblique | external spermatic fascia |
| Specific nerve from which the sural nerve arises | tibial nerve |
