Example Question #505 : Nclex
Which of the following is not a fossa of the scapula?
The subscapular fossa
The infraspinatus fossa
The suprascapular fossa
The supraspinous fossa
The suprascapular fossa
The scapula has multiple fossa that serve as attachment points of various bones and muscles of the shoulder. Among these are the glenoid fossa, where the head of the humerus articulates with the scapula, the subscapular fossa, which is an attachment for the subscapularis muscle, the infraspinous fossa, to which the infraspinatus attaches, and the supraspinous fossa, to which the supraspinatus muscle attaches. There is no suprascapular fossa on the scapula.
Example Question #22 : Bone Identification
What is the name of the bone that forms the lower part of the jaw?
The zygomatic bone
The maxilla
The frontal bone
The mandible
The mandible
The bone that forms the lower part of the jaw is the mandible. It is the largest and most inferior bone in the face, and articulates with the temporal bones at the temporomandibular joints. The maxilla forms the upper jaw, while the zygomatic bone forms the cheek and part of the orbit.
Example Question #506 : Nclex
All of the following bones of the skull help form the orbit except __________.
the sphenoid
the maxilla
the palatine bone
The temporal bone
The temporal bone
The orbit is formed by the following bones: the maxilla, the zygomatic bone, the frontal bone, the lacrimal bone, the ethmoid, the sphenoid, and the palatine bone. The temporal bone meets the zygomatic and sphenoid but does not form part of the orbit.
Example Question #507 : Nclex
All of the following bones form the nasal cavity except __________.
the sphenoid
the maxilla
the vomer
the nasal bone
the sphenoid
The nasal cavity is formed by the following bones: the maxilla, the vomer, the nasal bone, the palatine bones, the lacrimal bone, and the ethmoid bone. It is also formed by the nasal conchae and the septal cartilage. The sphenoid forms part of the orbit and multiple sinuses but does not form any art of the nasal cavity directly.
Example Question #511 : Nclex
You are taking care of a 22-year old basketball player who fractured his clavicle while playing in a game. Which of the following blood vessels is most likely to be compromised by the fractured bone?
Jugular vein
External carotid artery
Facial artery
Internal carotid artery
Subclavian artery
Subclavian artery
The correct answer is "subclavian artery." This is the correct answer because what this question is essentially asking is which of the listed blood vessels is closest to the clavicle, and most likely to be injured by a clavicular fracture based upon its proximity to the clavicle. Of the listed vessels, the subclavian artery is located closest to the clavicle (just inferior to the clavicle bone, as the name, sub-clavian implies). As such, if the clavicle breaks and a sharp fragment is formed, it would be most likely to injure the subclavian artery.
The internal and external carotid arteries, and jugular vein are located within the neck, but more deep and superior to the clavicle than the subclavian artery. The facial artery is located within the face and as such is located very superiorly to the clavicle bone and is unlikely to be involved by a clavicle fracture.
