What does radial styloid mean?
The radial styloid process is a projection of bone on the lateral surface of the distal radius bone.
What is radial styloid fracture?
A chauffeur fracture happens when the end of the radius bone (radial styloid process) in your forearm breaks. Chauffeur fractures occur from trauma because of falls, accidents or sports injuries.
What is the function of radial styloid process?
The radial styloid process projects obliquely downward from the distal end of the radius. It serves as the point of attachment for the brachioradialis muscle and the radial collateral ligament. Laterally, the tendons of extensor pollicis brevis and abductor pollicis longus run in a flat groove.
Where is the radial styloid bone?
distal radius bone
The radial styloid process is a projection of bone on the lateral surface of the distal radius bone. It extends obliquely downward into a strong, conical projection. The tendon of the brachioradialis attaches at its base, and the radial collateral ligament of the wrist attaches at its apex.
What is a styloid?
The styloid process is a cylindrical, slender, needle-like projection of varying lengths averaging 2 to 3 cm. The styloid process projects from the inferior part of the petrous temporal bone and offers attachment to the stylohyoid ligament and the stylohyoid, stylopharyngeus, and styloglossus muscles.
What does the radius do?
The radius’ main functions are to articulate with the ulna and humerus at the elbow to provide supination and pronation. Then to articulate with the lunate and scaphoid to provide all the movements of the wrist.
What is the radius bone made of?
The radius is classified structurally as a long bone because it is much longer than it is wide. Like all long bones, the radius is made of compact bone with a hollow center and spongy bones filling the ends. Compact bone is the hardest and heaviest part of the radius and makes up most of its structure.
Is styloid a bone?
Styloid process is derived from the Greek word stylos, meaning a pillar. The structure is a long, cylindrical, cartilaginous bone located on the inferior aspect of temporal bone, posterior to the mastoid apex, anteromedial to the stylomastoid foramen, and lateral to the jugular foramen and carotid canal.
What are styloglossus and stylohyoid?
The stylohyoid muscle connects to the posterior belly of the digastric muscle in its path. It lies anteromedial to the superior margin of the posterior belly of the digastric muscle. The styloglossus muscle lies medially and anterior to the stylohyoid muscle.
What is radius bone?
radius, in anatomy, the outer of the two bones of the forearm when viewed with the palm facing forward. All land vertebrates have this bone. In humans it is shorter than the other bone of the forearm, the ulna.
