a. Trapezius
b. Rhomboideus major
c. Rhomboideus minor
d. Levator scapulae
ANSWER: D
The scapula, also known as the shoulder blade, is a flat triangular bone located at the back of the trunk and resides over the posterior surface of ribs two to seven.
Muscles that originate from scapula
- Deltoid
- Supraspinatus
- Infraspinatus
- Triceps brachii (long head)
- Teres minor
- Teres major
- Latissimus dorsi
- Coracobrachialis
- Biceps brachii
- Subscapularis
- Omohyoid muscles
Muscles that insert on the scapula
- Trapezius
- Levator scapulae
- Rhomboid major
- Rhomboid minor
- Serratus anterior
- Pectoralis minor muscles
2. Infection from facial vein spread to cavernous sinus because
a. Venous connection do not have value
b. Value are stretched on opening
c. Facial vein opens into interior jugular vein
d. Ophthalmic vein
ANSWER: A
3. Painful sensations from ethmoid sinus are transmitted by
a. Frontal
b. Nasociliary
c. Infratrochlear
d. Lacrimal
ANSWER: B
The ethmoid sinus is situated between the orbit and the nose. The ethmoid sinus is present at birth and continues to enlarge with facial development
NERVE SUPPLY
- The anterior and posterior ethmoid nerves provide innervation to ethmoid sinuses.
- The posterior ethmoidal nerve is a nerve of the orbit around the eye.
- It is a branch of the nasociliary nerve from the ophthalmic nerve (CN V1).
- It supplies sensation to the sphenoid sinus, the ethmoid sinus, and part of the dura mater in the anterior cranial fossa.
BLOOD SUPPLY
- The ethmoid sinuses are supplied by the anterior and posterior ethmoid arteries, respectively.
- These arteries are branches of the ophthalmic artery, a branch of the internal carotid artery.
- Ethmoid sinus venous drainage is done by the maxillary and ethmoid veins
4. Claw hand deformity occurs due to lesion of
a. ulnar
b. radial
c. Median
d. Axillary
ANSWER: A
Claw Hand deformity is a condition where the fingers are bent into a position that looks like a claw.
It may affect all of the fingers or only some of them depending on its cause. The fingers are usually bent or curved and the deformity can affect one hand or both hands.
Claw Hand is a hand deformity with hyperextension of the metacarpophalengeal (MCP) joints and flexion of the interphalengeal (IP) joints due to weakness of the intrinsic muscles of the hand.
CAUSES
- Nerve damage in the arm e.g ulnar palsy, ulnar tunnel syndrome.
- Congenital birth defect.
- Some genetic diseases such as Charcot-Marie-Tooth Disease.
- Bacterial infections such as Leprosy.
- Scarring after a severe hand or forearm burn.
- Compartment syndrome of the hand.
TYPES
- Complete when it involves all the digits and therefore results from both Ulnar and Median Nerve Palsy.
- Incomplete or Partial where it involves only ulnar 2 digits and is referred to as an isolated Ulnar Nerve Palsy
