What type of bone is the Carpals?

What type of bone is the Carpals?

Short Bones
Short Bones Are Cube-shaped The carpals in the wrist (scaphoid, lunate, triquetral, hamate, pisiform, capitate, trapezoid, and trapezium) and the tarsals in the ankles (calcaneus, talus, navicular, cuboid, lateral cuneiform, intermediate cuneiform, and medial cuneiform) are examples of short bones.

What are metacarpals and metatarsals?

Bones of the hand, showing the carpal bones (wrist bones), metacarpal bones (bones of the hand proper), and phalanges (finger bones). In humans the metatarsal bones, those of the foot proper, are larger than the corresponding bones of the hands, the metacarpal bones.

What are the 7 tarsal bones?

The tarsal bones are 7 in number. They are named the calcaneus, talus, cuboid, navicular, and the medial, middle, and lateral cuneiforms.

What is the function of carpals?

The carpal bones allow the wrist to move and rotate vertically.

Are carpals short or irregular bones?

Short bones, such as the carpals, are approximately equal in length, width, and thickness. Flat bones are thin, but are often curved, such as the ribs. Irregular bones such as those of the face have no characteristic shape. Sesamoid bones, such as the patellae, are small and round, and are located in tendons.

What are the metatarsals?

The metatarsal bones are the bones of the forefoot that connect the distal aspects of the cuneiform (medial, intermediate and lateral) bones and cuboid bone to the base of the five phalanges of the foot. There are five metatarsal bones, numbered one to five from the hallux (great toe) to the small toe.

Are metatarsals toes?

The metatarsal bones, or metatarsus, are a group of five long bones in the foot, located between the tarsal bones of the hind- and mid-foot and the phalanges of the toes.

What are the 8 tarsal bones?

The tarsal bones are found in the ankle and include the calcaneus, talus, navicular, medial, intermediate and lateral cuneiform and cuboid [Figure 1B].

What are the 14 tarsal bones?

The tarsus

• Talus. Talus (Latin for ankle) talus is the most superior bone of the tarsus and rests on top of the calcaneus.
• Calcaneus. The calcaneus is often referred to as the heel bone and is the largest and strongest bone of the foot.
• Cuboid.
• Navicular.
• Cuneiforms.

Where are carpals located?

Wrist
Your wrist is made up of eight small bones (carpal bones) plus two long bones in your forearm — the radius and the ulna. The most commonly injured carpal bone is the scaphoid bone, located near the base of your thumb.

What are carpals and metacarpals?

The eight, irregularly shaped carpals are the most proximal bones of the hand. Metacarpal bones of the left hand: The metacarpals connect the carpal bones of the wrist with the phalanges (finger bones). The capitate articulates with the scaphoid and lunate proximally and the third and fourth metacarpal.

Is the metatarsal part of the foot?

metatarsal: A bone from the center of the foot that articulates with the tarsals and phalanges. tarsal: A bone forming part of the ankle or heel. The foot contains 26 bones that are divided into three regions: the tarsals (or ankle and heel), the metatarsals (forming the sole of the foot), and the phalanges (forming the digits).

How are the medial and lateral retinacula attached to the patella?

The medial and lateral retinacula, which are extensions of the quadriceps muscle, bypass the patella and insert directly on the tibia. If the retinacula are intact after a patellar fracture, the patient is able to extend the knee actively. The primary blood supply of the patella enters the central portion and the distal pole.

What are the different types of Patella fractures?

Fractures of the patella are broadly classified as transverse, stellate or comminuted, vertical, and osteochondral. Any of these fracture types can be displaced or nondisplaced. Transverse fractures are the most common type followed by stellate fractures. The majority of transverse fractures are in the lower third of the patella.

What muscles attach to the patella?

The patella is generally triangular, with the apex pointing distally. The rectus femoris and vastus muscles (lateralis, medialis, intermedius) all insert on the proximal pole. The patellar ligament attaches to the distal pole of the patella and inserts on the tibial tuberosity.
