What is distal to metacarpal

Each metacarpal bone consists of a body or shaft, and two extremities: the head at the distal or digital end (near the fingers), and the base at the proximal or carpal end (close to the wrist).

Are the Carpals distal to the metacarpals?

The hand contains five metacarpal bones that articulate proximally with the carpals and distally with the proximal phalanges.

Which bone is most distal?

Phalanges, the digits of the hand, are the most distal bones of the upper limb. The humerus is the bone of the upper arm. The ulna is the bone of the medial side of the forearm. The radius is the bone of the lateral side of the forearm.

Which bone is immediately distal to the second metacarpal?

The trapezium articulates with the scaphoid proximally and the first, thumb, and second metacarpal distally. The trapezoid articulates with the scaphoid proximally and the second metacarpal distally.

What's metacarpal bone?

metacarpal, any of several tubular bones between the wrist (carpal) bones and each of the forelimb digits in land vertebrates, corresponding to the metatarsal bones of the foot. … The metacarpals also form a transverse arch that allows the fingertips and thumb to be brought together for manipulation.

Which bone is the scapula?

The scapula is a flat, triangular-shaped bone (colloquially as the “shoulder blade“). It is located in the upper thoracic region on the dorsal surface of the rib cage. It connects with the humerus at the glenohumeral joint as well as the clavicle at the acromioclavicular joint to form the shoulder joint.

What kind of bone is the metacarpal?

Medical Definition of Bone type Short bones: Short bones also have a tubular shaft and articular surfaces at each end but are much smaller. The short bones include all of the metacarpals and phalanges in the hands, and the metatarsals and phalanges in the feet. Flat bones: Flat bones are thin and have broad surfaces.

Which carpal bone is the most medial of the distal row of Carpals?

Both the term hamate and unciform refer to the hook-like appendage of this bone. It is the most medial of the carpals in the distal row and articulates with five bones – the fourth and fifth metacarpals distally, the lunate and triquetral proximally and medially and the capitate laterally.

What bones are distal to the radius and ulna and proximal to the metacarpals?

The Hand. The wrist consists of a series of short bones that are located distal to the ulna and radius, and proximal to the metacarpals. Within this small area of bones, there are various articulating surfaces within the wrist.

What type of bone is metatarsal?

The five metatarsals are dorsally convex long bones consisting of a shaft or body, a base (proximally), and a head (distally). The body is prismoid in form, tapers gradually from the tarsal to the phalangeal extremity, and is curved longitudinally, so as to be concave below, slightly convex above.

What are the 14 phalanges bones?

The phalanges are the bones that make up the fingers of the hand and the toes of the foot. There are 56 phalanges in the human body, with fourteen on each hand and foot. Three phalanges are present on each finger and toe, with the exception of the thumb and large toe, which possess only two.

Is the humerus bone inferior lateral and distal?

Humerus and Elbow Joint The humerus is the single bone of the upper arm region. … Distally, the humerus becomes flattened. The prominent bony projection on the medial side is the medial epicondyle of the humerus. The much smaller lateral epicondyle of the humerus is found on the lateral side of the distal humerus.

What is the name of the distal bone of the UE on the medial side?

On the medial side of the distal radius is the ulnar notch of the radius. This shallow depression articulates with the head of the ulna, which together form the distal radioulnar joint.

What is distal row?

row toward the fingers, or distal row, includes the trapezium (greater multangular), trapezoid (lesser multangular), capitate, and hamate. The distal row is firmly attached to the metacarpal bones of the hand.

Are the hand distal or proximal to the arm?

Your hand is further away from your torso than your elbow. Therefore your hand is “distal” when compared to your elbow. … The wrist is closer to the torso than the fingers. Therefore it is “proximal” when compared to your fingers.

Where is the 5th metacarpal bone located?

The fifth metacarpal bone (metacarpal bone of the little finger or pinky finger) is the most medial and second-shortest of the metacarpal bones.

Which is the first metacarpal bone?

Anatomical terms of bone The first metacarpal bone or the metacarpal bone of the thumb is the first bone proximal to the thumb. It is connected to the trapezium of the carpus at the first carpometacarpal joint and to the proximal thumb phalanx at the first metacarpophalangeal joint.

What is the 4th metacarpal?

The fourth metacarpal bone (metacarpal bone of the ring finger) is shorter and smaller than the third. The base is small and quadrilateral; its superior surface presents two facets, a large one medially for articulation with the hamate, and a small one laterally for the capitate.

What is the tibia bone?

Tibia and fibula are the two long bones located in the lower leg. The tibia is a larger bone on the inside, and the fibula is a smaller bone on the outside. The tibia is much thicker than the fibula. It is the main weight-bearing bone of the two.

Which bone feature of the scapula is posterior?

Spine – the most prominent feature of the posterior scapula. It runs transversely across the scapula, dividing the surface into two.

What is clavicle bone?

The clavicle is located between the ribcage (sternum) and the shoulder blade (scapula). It is the bone that connects the arm to the body. The clavicle lies above several important nerves and blood vessels. However, these vital structures are rarely injured when a fracture occurs.

What is humerus bone?

The humerus — also known as the upper arm bone — is a long bone that runs from the shoulder and scapula (shoulder blade) to the elbow. … A humerus shaft fracture, on the other hand, is one that is localized at the mid portion of the upper arm.

Which carpal bone is medial and distal to the ulna bone?

The proximal row of carpal bones (moving from radial to ulnar) are the scaphoid, lunate, triquetrum, and pisiform, while the distal row of carpal bones (also from radial to ulnar) comprises the trapezium, trapezoid, capitate, and hamate.

What is distal radius?

The radius is one of two forearm bones and is located on the thumb side. The part of the radius connected to the wrist joint is called the distal radius. When the radius breaks near the wrist, it is called a distal radius fracture.

What are the distal row of the wrist bones?

The bones of the distal row are the trapezium, the trapezoid, the capitate, and the hamate. The capitate and part of the hamate project proximally. The bases of the five metacarpals articulate with the distal row of carpal bones.

Which bone lies directly proximal to the first metacarpal?

The capitate is found within the distal row of carpal bones. The capitate lies directly adjacent to the metacarpal of the ring finger on its distal surface, has the hamate on its ulnar surface and trapezoid on its radial surface, and abuts the lunate and scaphoid proximally.

Which bone articulates with the 4th metacarpal?

The first metacarpal articulates with the trapezium. The second metacarpal articulates with the trapezium, trapezoid and capitate. The third articulates with the capitate. The fourth and fifth articulate with the hamate.

Which of the following is NOT a distal tarsal bone?

The bone that is not a tarsal bone is d) Pisiform. The pisiform bone is a carpal bone, which is found in the wrist. Calcaneous, cuboid and navicular…

Where is the 4th metatarsal bone?

The fourth metatarsal. (Left.) As the four other metatarsals bones it can be divided into three parts; base, body and head. The base is the part closest to the ankle and the head is closest to the toes.

What are metatarsal guards?

Metatarsal guards are a form of personal protective equipment (PPE) that protect the top of the foot from compression injuries. They consist of guards that fit over the instep of the foot protecting it from heavy weights.
