The talus is the tarsal bone that articulates superiorly with the tibia and fibula, forming the ankle joint.
Missing Word
talus
The talus is one of the seven tarsal bones and is unique among them because it is the only tarsal bone that articulates directly with the bones of the lower leg, the tibia and fibula. This articulation forms the talocrural joint, commonly known as the ankle joint, which is crucial for dorsiflexion and plantarflexion of the foot.

Question 2
Each finger, except the thumb, contains three phalanges: a proximal, a middle, and a distal.
Missing Word
distal
Phalanges are the bones of the fingers and toes. In the hand, each of the four fingers (digits 2-5) has three phalanges: a proximal phalanx, a middle phalanx, and a distal phalanx. The thumb (digit 1) is an exception, having only a proximal and a distal phalanx.

Question 3
The superior, largest portion of the hip bone, which forms the prominent flare of the pelvis, is the ilium.
Missing Word
ilium
The ilium is the broad, flaring superior part of the hip bone, contributing to the formation of the pelvic girdle. It is the largest of the three bones (ilium, ischium, and pubis) that fuse to form the os coxa, and its superior crest is palpable.

Question 4
The flat, triangular bone located on the posterior aspect of the thorax, commonly known as the shoulder blade, is the scapula.
Missing Word
scapula
The scapula, or shoulder blade, is a large, triangular flat bone that lies on the posterior surface of the rib cage. It articulates with the humerus and clavicle, providing a movable base for the upper limb and serving as an attachment point for many muscles.
Category: Pectoral Girdle
Question 5
The cuboid bone contributes to both the lateral longitudinal arch and the transverse arch of the foot.
Missing Word
cuboid
The cuboid bone is one of the seven tarsal bones, located on the lateral side of the foot. It plays a significant role in supporting the lateral longitudinal arch and is also an important component of the transverse arch, contributing to the foot's overall stability and flexibility.
Category: Arches of the Foot
Question 6
The proximal end of the fibula, known as the head, articulates with the lateral condyle of the tibia.
Missing Word
head
The head of the fibula is the enlarged, superior end of the fibula. It forms the proximal tibiofibular joint by articulating with the lateral condyle of the tibia, but it does not bear weight. It serves as an attachment point for various muscles and ligaments.
Category: Tibia and Fibula
Question 7
The largest of the tarsal bones, which forms the heel of the foot, is the calcaneus.
Missing Word
calcaneus
The calcaneus is the largest and strongest of the tarsal bones. It forms the posterior prominence of the heel and plays a crucial role in weight bearing, transmitting the body's weight from the talus to the ground.
Category: Foot
Question 8
The distal end of the radius features a prominent pointed projection that extends further distally than the comparable projection on the ulna.
Missing Word
radius
The radius is the lateral bone of the forearm. Its distal end bears a prominent styloid process, which extends distally further than the styloid process of the ulna, helping to stabilize the wrist joint laterally.
Category: Radius and Ulna
Question 9
The most lateral bone in the proximal row of carpals, which articulates with the radius and is commonly fractured, is the scaphoid.
Missing Word
scaphoid
The scaphoid is one of the eight carpal bones located in the wrist, forming part of the proximal row. It is situated on the thumb side of the wrist and articulates proximally with the radius. Due to its position and shape, it is the most frequently fractured carpal bone.
Category: Hand
Question 10
The five long bones that form the main body of the foot, connecting the tarsals to the phalanges, are called the metatarsals.
Missing Word
metatarsals
The metatarsals are a group of five long bones in the foot, situated between the tarsal bones of the hindfoot and midfoot and the phalanges of the toes. They are numbered I to V, starting from the medial side. These bones provide a framework for the foot and help distribute body weight during locomotion.
Category: Foot
Question 11
The boat-shaped tarsal bone located between the talus posteriorly and the cuneiforms anteriorly is the navicular.
Missing Word
navicular
The navicular bone is one of the seven tarsal bones, characterized by its distinctive boat-like shape. It is positioned on the medial side of the foot, articulating with the talus proximally and the three cuneiform bones distally. This bone contributes to the stability of the medial longitudinal arch of the foot.
Category: Foot
Question 12
The large, cup-shaped socket on the lateral aspect of the hip bone that articulates with the head of the femur is the acetabulum.
Missing Word
acetabulum
The acetabulum is the deep, cup-shaped depression on the lateral surface of the hip bone. It serves as the articulation point for the head of the femur, forming the hip joint. This robust socket provides stability for weight-bearing and movement.
Category: Pelvic Girdle
Question 13
The largest sesamoid bone in the body, which is embedded within the quadriceps femoris tendon and protects the knee joint, is the patella.
Missing Word
patella
The patella, commonly known as the kneecap, is a triangular sesamoid bone located anterior to the knee joint. It functions to protect the knee and to increase the leverage of the quadriceps femoris muscle during knee extension. It is the largest sesamoid bone in the human body.
Category: Femur and Patella
Question 14
The lateral expansion of the spine of the scapula, which articulates with the clavicle, is the acromion.
Missing Word
acromion
The acromion is a prominent bony projection from the scapula that forms the highest point of the shoulder. It serves as an articulation point for the clavicle, forming the acromioclavicular joint.
Category: Pectoral Girdle
Question 15
The distal end of the humerus features the medial and lateral epicondyles which are bony projections above the condyles, providing attachment points for forearm muscles and ligaments.
Missing Word
epicondyles
The epicondyles are prominent bony projections located on either side of the distal humerus, just superior to the condyles. They serve as important attachment sites for muscles and ligaments of the forearm, facilitating various movements at the elbow joint.
