Which is not part of your appendicular skeleton?
Ulna.
Ethmoid bone.
Ilium.
Patella.
The Correct Answer is B
The ethmoid bone is a part of the axial skeleton, not the appendicular skeleton.
The axial skeleton consists of the bones of the skull, vertebral column, ribs, and sternum.
Choice A is incorrect because the ulna is a part of the upper limb, which is supported by the pectoral girdle.
Choice C is incorrect because the ilium is a part of the hip bone, which forms the pelvic girdle.
Choice D is incorrect because the patella is a part of the lower limb, which is supported by the pelvic girdle.

Correct Answer is ["condylar process of the mandible"]
Explanation
The mandible condylar process is a bony projection located at the posterior aspect of the mandible, which is the lower jawbone.
It is a rounded, knob-like structure that articulates with the temporal bone of the skull, forming the temporomandibular joint (TMJ).
The condylar process allows for movements of the mandible, including opening and closing the mouth and chewing food.
The shape and position of the condylar process can affect the function of the TMJ and can contribute to conditions such as TMJ disorders.
Correct Answer is ["Scaphoid bone"]
Explanation
The carpal bones, also known as the wrist bones, are a group of eight small bones located in the wrist joint.
They are arranged in two rows of four bones each, with the rows separated by a space known as the carpal tunnel.
The carpal bones are held together by ligaments, and their shape and arrangement allow for a wide range of wrist movements.
The names of the carpal bones, from the proximal row to the distal row, are the scaphoid, lunate, triquetrum, and pisiform, and the trapezium, trapezoid, capitate, and hamate.
Each bone has a unique shape and surface features that allow it to articulate with adjacent bones, forming a complex network of joints that are important for wrist and hand movements.
The carpal bones are important because they provide stability to the wrist joint, allowing for precise movements of the hand and fingers.
They also help to transfer forces from the hand to the forearm, and vice versa.
Injuries to the carpal bones can result in wrist pain, instability, and decreased function of the hand and fingers.
Additionally, the arrangement of the carpal bones can affect the function of the median nerve, which runs through the carpal tunnel.
Compression or irritation of this nerve can result in carpal tunnel syndrome, a condition characterized by pain, numbness, and tingling in the hand and fingers.
