Shoulder / Arm
Name the 4 rotator cuff muscles.
Supraspinatus, infraspinatus, teres minor, subscapularis.
Which nerve passes deep to the flexor retinaculum and, when compressed, contributes to carpal tunnel syndrome?
Median nerve
Which muscle can be palpated directly inferior of the ASIS?
What is the Tensor Fascia Latae
This muscle is known for "unlocking" the knee joint from an extended position.
Popliteus
To feel the ligamentum nuchae change tension underneath your fingers, what passive movement can you perform at the head?
What is flexion and extension
Name all 4 joints that contribute to the shoulder complex.
Sternoclavicular joint, scapulothoracic joint, acromioclavicular joint, glenohumral joint.
What is the natural action of the extrinsic digital flexor muscles called that can help produce a functional grasp for some patients with quadriplegia?
Tenodesis grasp.
What innervates the gluteus minimus?
What is the superior gluteal nerve
What are the (2) insertions of the tibialis anterior?
Medial cuneiform and base of the first metatarsal.
Which muscle works to rotate the spine towards the same side?
What is the internal oblique
What nerve innervates the subscapularis?
Upper and lower subscapular nerves
Describe the insertional differences between the flexor digitorum superficialis (FDS) and the flexor digitorum profundus (FDP).
(FDS): Inserts onto the sides of the middle phalanges of digits 2–5. Primarily flexes the proximal interphalangeal (PIP) joints.
(FDP): Inserts onto the palmar bases of the distal phalanges of digits 2–5. Primarily flexes the distal interphalangeal (DIP) joints.
The FDS tendon splits into two slips, allowing the FDP tendon to pass through and insert more distally.
This powerful, multi-joint muscle is the only member of the quadriceps femoris group that crosses the hip joint, allowing it to both flex the thigh and extend the knee
What is the rectus femoris
Describe the unique differences in insertion between the fibularis longus and brevis.
Fibularis longus courses beneath the plantar aspect of the foot to insert on the medial cuneiform and base of the 1st metatarsal, whereas fibularis brevis inserts on the tuberosity of the 5th metatarsal.
Which muscle acts as a synergist with the internal oblique during flexion of the vertebral column?
What is the external oblique
What is the origin of the levator scapula?
Transverse processes of first through fourth cervical vertebrae.
Name the 3 muscles of the hypothenar eminence and their innervation.
Abductor digiti minimi, flexor digiti minimi brevis, opponens digiti minini. Innervation is ulnar nerve.
The three ligaments that reinforce the hip joint capsule are:
Iliofemoral ligament (Y-ligament of Bigelow)
Pubofemoral ligament
Ischiofemoral ligament
Name all (3) components of eversion and all (3) components of inversion.
Eversion (Pronation):
Eversion
Abduction
Dorsiflexion
Inversion (Supination):
Inversion
Adduction
Plantarflexion
The three muscular layers of the lateral abdominal wall, from superficial to deep, are:
And then what's deep to that?
External oblique
Internal oblique
Transversus abdominis
Abdominal viscera
From superior to inferior, list all of the terminal branches of the brachial plexus.
Musculocutaneous nerve
Axillary nerve
Radial nerve
Median nerve
Ulnar nerve
Name the four short intrinsic muscles associated with the thenar eminence.
Abductor pollicis brevis, flexor pollicis brevis, opponens pollicis, adductor pollicis.
Name all 6 muscles of the deep hip rotators and specify which the sciatic nerve exits from.
Piriformis, Superior gemellus, Obturator internus, Inferior gemellus, Obturator externus, Quadratus femoris
Sciatic nerve passes beneath Piriformis, or through in some cases
Name the various structures (6) that pass through the tarsal tunnel.
Tibialis posterior, flexor digitorum longus, tibial artery and vein, tibial nerve, flexor hallucis longus.
Name all of the muscles included within the "paraspinals"
Erector spinae (3), transverospinalis group (3), and muscles learned today (2)
1. Erector Spinae: Iliocostalis, Longissimus, Spinalis
2. Transversospinalis: Semispinalis, Multifidus, Rotatores
3. Segmental Muscles: Interspinales, Intertransversarii
