The jaw bone articulates with the temporal bone at what fossa?
The jaw bone articulates with the temporal bone at the mandibular fossa, also known as the glenoid fossa or the mandibular fossa of the temporal bone. This is where the temporomandibular joint is formed, allowing for movements of the jaw.
Which portion of the temporal bone articulates with the jawbone?
at the mandibular fossa
Mandibular fossa of temporal bone?
The mandibular fossa is a depression on the underside of the temporal bone where the lower jaw (mandible) articulates to form the temporomandibular joint (TMJ). This joint allows for jaw movement during activities like chewing and speaking. The mandibular fossa is lined with cartilage and acts as a cushion to reduce friction during jaw movements.
What bones does the maxilla articulate with?
The mandibular condyle articulates with the mandibular fossae of the temporal bone.
A slight side-shift of the mandible in the mandibular fossa is referred to as?
dislocation
What keeps the mandibular condyle from slipping out of its fossa in a posterior direction?
The articular disc of the temporomandibular joint acts as a cushion and helps maintain the mandibular condyle in position within the fossa. Ligaments, muscles, and the shape of the condyle and fossa also contribute to stabilizing the joint and preventing the condyle from slipping posteriorly.
What is the name of a shallow basin-like depression in a bone?
Fossa = Shallow depression or dip in the surface of a bone Process = Bone marking which stick out from the rest of the bone
What bone of the skull has two heads?
The hyoid bone, located in the neck, is the only bone in the body that does not articulate with any other bone. It has a body and two pairs of horns, or greater and lesser horns, giving it a two-headed appearance.
What is the depression on the surface of a bone called?
The depression on the surface of a bone is called a fossa. It is a shallow, basin-like structure that typically serves as an attachment site for muscles or tendons.
The jaw joint is an articulation of?
The jaw joint, also known as the temporomandibular joint, is an articulation of the mandible (lower jaw bone) with the temporal bone of the skull. It allows for movements such as opening and closing the mouth, chewing, and speaking. Dysfunction of the temporomandibular joint can result in pain and difficulty with these functions.
How many glenoid fossa in the human body?
Four. The glenoid fossa of each scapula and of each temporal bone.
Is the lacrimal bone and lacrimal fossa the samething?
No, the lacrimal bone is a small, fragile bone that contributes to the bony orbit of the eye, while the lacrimal fossa is a depression on the medial wall of the orbit that houses the lacrimal sac, which is responsible for draining tears from the eyes.
