What connects the hand to the forearm?
The wrist joint is the complex joint formed between the distal ends (furthest from the body) of the Radius and Ulna (two forearm bones) and the carpal bones. It connects the forearm to the hand and allows a good range of motion.
What is the region of the forearm called?
It is homologous to the region of the leg that lies between the knee and the ankle joints, the crus. The forearm contains two long bones, the radius and the ulna, forming the two radioulnar joints. The interosseous membrane connects these bones….

What joint is between the forearm and wrist?
radiocarpal joint
The wrist joint also referred to as the radiocarpal joint is a condyloid synovial joint of the distal upper limb that connects and serves as a transition point between the forearm and hand.
What is the shorter bone in the forearm?
Within the forearm, the radius is positioned laterally and is the shorter of the two bones. The radial head has two points of articulation proximally: the radiocapitellar joint, articulating with the capitulum of the distal humerus, and the radial notch of the ulna where it also has support from the annular ligament.
What is the part of the hand between the thumb and index finger?
The area of skin between the thumb and the index finger is often call the “thenar webspace”. What the “webspace” looks like when a child is performing fine motor tasks is often a good indicator of muscle strength and fine motor control.
Where is the forearm tendon?
Flexor carpi ulnaris (FCU) tendon Its muscle belly is in the forearm. The tendon travels along the inside of the forearm on the side of the small finger and crosses the wrist. It attaches to the wrist bone, the pisiform, and as well as the 5th hand bone.
What region is the forearm in anatomy?
Forearm. The forearm is the region between the elbow and wrist joint. It comprises two bones, the radius and the ulna. The brachial artery divides into the radial and ulnar, which run down the forearm on their respective sides.
What is the wrist region called?
carpus
In human anatomy, the wrist is variously defined as (1) the carpus or carpal bones, the complex of eight bones forming the proximal skeletal segment of the hand; (2) the wrist joint or radiocarpal joint, the joint between the radius and the carpus and; (3) the anatomical region surrounding the carpus including the …
What is the inner wrist called?
The carpus is formed from eight small bones collectively referred to as the carpal bones. The carpal bones are bound in two groups of four bones: the pisiform, triquetrum, lunate and scaphoid on the upper end of the wrist. the hamate, capitate, trapezoid and trapezium on the lower side of the hand.
What is inside of wrist called?
Carpal bones in the wrist Your wrist is made up of eight small bones called the carpal bones, or the carpus. These join your hand to the two long bones in your forearm — the radius and ulna. The carpal bones are small square, oval, and triangular bones.
Which bone in the forearm region is on the pinky finger side?
The forearm is made up of two bones: the radius and the ulna. The radius is on the “thumb side” of the forearm, and the ulna is on the “pinky finger side.”
What is the inner and larger bone of the forearm?
The inner and larger bone of the forearm located on the side of the little finger is the. Ulna.
Which is the connection point between the arm and the hand?
Wrist: The connection point between the arm and the hand, the wrist enables hand movements. Each hand consists of 19 bones. The palm includes five metacarpals, and each finger except the thumb contains one proximal phalanx, one middle phalanx, and one distal phalanx.
Where is the triquetrum located in the hand?
The triquetrum is a bone on the small finger side of the wrist in the first row of wrist bones. This bone adds stability to the wrist, gives the wrist a larger surface to bear weight transmitted from the hand, and makes a joint with other carpal bones including the pisiform.
Where are the fingers located on the hand?
Fingers: Digits that extend from the palm of the hand, the fingers make it possible for humans to grip the smallest of objects. Palm: This is the bottom of the body of the hand.
Is the radius on the thumb side of the hand?
The radius is one of the two forearm bones and is on the thumb side of the forearm near the hand, but is always on the outside of the elbow. The position of the radius changes depending on how the hand is turned because the radius twists around the other forearm bone, the ulna.
