Document Summary

Lab #11 nervous system anatomy, reflex actions, and motor learning. Briefly describe the muscle groups innervated by each of the somatic nerves listed: Median nerve most flexors in the forearm. Musculoskeletal nerve biceps brachii, brachialis, coracobrachialis. Ulnar nerve flexor digitorum profudus (pinky finger and ring finger), flexor carpi ulnaris. Radial nerve triceps brachii, anconeus, brachioradialis, extensor carpi radialis longus. Femoral nerve anterior compartment of thigh. Sciatic nerve lateral rotator group (except piriformis and quadratus femoris), posterior compartment. Tibial nerve (medial) abductor halluces, flexor digitorum brevis, flexor halluces brevis, first lumbrical. Common peroneal nerve anterior compartment of leg, lateral compartment of leg, extensor digitorum of thigh brevis. Respiratory function ceases and person will die if they don"t receive medical attention. 31 pairs of spinal nerves that are grouped according to where they leave the vertebral column. 33 vertebrae 7 cervical, 12 thoracic, 5 lumbar, 5 fuse to form sacrum, 4 coccygeal which form tailbone.

a.) flexion of the forearm

b.) supination of the forearm/wrist

2. The flexor digitorum superficialis muscle of the anteriorcompartment of the forearm flexes the distal phalanges (T or F)

a.) if false, the name of what muscle would make the statementtrue

3. List three similarities between the muscles of the foot,regarding their structure, orientation, functions, and/ornames.

For muscle anatomy identification, you will need to identify thename of the muscle, the origin, the insertion, and the action ofthe muscle labeled on the models. You can find origins/insertionsin your lab manual, but you can also find the specific origins andinsertions we are looking for on the laminated cards for the claymodeling in lab. For actions, please identify the primary action ofthe muscle. For example for the gluteus maximus, the primaryactions are extension and rotation of the hip and maintain kneeextension. Many muscles also perform other actions in which theyare supporting other muscles. You do not have to include these,just focus on primary action. Please make sure you also know theindividual muscles of the iliopsoas, quadriceps, hamstrings, andpelvic floor.

iliopsoas (psoas major and iliacus)

gluteus maximus

gluteus medius

sartorius

adductor longus

adductor magnus

gracilis

quadriceps femoris (rectus femoris, vastuslateralis, vastus medialis, vastus intermedius)

hamstrings (biceps femoris, semitendinosus,semimembranosus)

pelvic floor (levator ani and external urethralsphincter)- NO origins and insertions assessed for thesemuscles, just identification on models and actions.

Flexor digitorum longus

fibularis longus (peroneus longus)

extensor digitorum longus

gastrocnemius

soleus

extensor hallucis longus

tibialis anterior

Also find: patellar ligament, calcanealtendon

damage to which spinal nerves might produce the following?
a) inability to flex the forearm with the biceps brachi muscle
b) inability to breathe
c) inability to flex the hip and extend the knee with the anterior thigh muscles
d)inability to extend the hip and flex the knee with the posterior thigh muscles
e)inability to move the hands or feels the skin over the medial hand
