Which joint in the body has the most range of motion?
The shoulder joint is called the glenohumeral joint.
This is a ball-and-socket joint formed by the articulation between the head of the humerus and the glenoid cavity of the scapula (Figure 7.3).
This joint has the largest range of motion of any joint in the body..
What is the DIP joint of the toe?
The metatarsal phalangeal joint (MTP joint) is the first joint that connects the toe to the foot. The second is the proximal interphalangeal joint (PIP joint), and the last is the distal interphalangeal joint (DIP joint). A joint capsule made of ligaments surrounds each joint and holds the bones together.
What type of joint is the proximal interphalangeal joint?
hinge jointThe proximal interphalangeal (PIP) joints of the fingers are extremely important for gripping things with hands, more specifically, what is called the ‘power’ grip. Being a hinge joint, the joint’s articular surface and soft tissue do not permit any lateral movement.
What kind of joint are toes?
The big toe has the metatarsophalangeal joint and one interphalangeal joint. A layer of cartilage covers the surfaces of the joints where the bones meet which allows them to glide smoothly with each other as they move. A thin membrane called the synovium encloses the joint and secretes a fluid to lubricate them.
Why is my PIP joint swollen?
What is a PIP joint dislocation or sprain? PIP joint dislocation occurs when trauma causes the bones in the middle joint of a finger to dislodge. This usually results in a very painful, swollen and bruised joint that does not move properly, if at all.
Are pinkies fingers?
The little finger, or pinky finger, also known as the fifth digit, or pinkie, is the most ulnar and smallest finger of the human hand, opposite the thumb, and next to the ring finger.
Which movements are available at the interphalangeal joints?
Movements. —The only movements permitted in the interphalangeal joints are flexion and extension; these movements are more extensive between the first and second phalanges than between the second and third.
What type of joint is dip?
The interphalangeal joints of the hand are synovial hinge joints that span between the proximal, middle, and distal phalanges of the hand.
Which joints can Hyperextend?

Does the thumb have a PIP joint?
Each of the digits, except the thumb, has three phalanges with three hinged joints: distal interphalangeal (DIP), proximal interphalangeal (PIP), and metacarpophalangeal (MCP) (figure 1), with a fingernail at the dorsal end (figure 2 and picture 1 and figure 3). … The thumb is discussed below (see ‘Thumb anatomy’ below).
Why is thumb not a finger?
Your thumb is different from your fingers. Your fingers have two joints and three bones called phalanges or phalanxes. A thumb only has one joint and two phalanges.
Why does the thumb only have 2 joints?
Thumbs only have two bones, so they’re obviously shorter, and they play a very important role that no other finger can claim; thanks to their unique saddle-like joint shape, and a little muscle known as the abductor pollicis brevis, you can bend and stretch your thumbs opposite your fingers to grip things.
What is a DIP joint on the finger?
The DIP joint is the first knuckle from the top of the finger. It connects the distal phalanx and middle phalanx, which are the two bones at the tip of the finger. Experiencing DIP joint pain is often a sign of a type of arthritis, such as osteoarthritis or psoriatic arthritis.
What extends the dip?
Muscles: interossei and lumbricals flex the MP while extending the PIP and DIP joints; flexor digitorum superficialis flexes the MP and PIP joints only, while flexor digitorum profundus flexes all three, and is the only muscle capable of flexing the DIP joint.
