What bones fits into the olecranon fossa?
the ulna fits into the olacranon fossa, specifically the olecranon process.
Bone that contains the olecranon fossa?
The bone that contains the olecranon fossa is the humerus, which is located in the upper arm. The olecranon fossa is a depression on the posterior side of the humerus that accommodates the olecranon process of the ulna when the arm is extended.
The coronoid fossa is on what side of the humerus?
The coronoid fossa is located on the anterior side of the humerus, which is the side facing towards the front of the body.
Which one of the following veins is found only in or below the AC fossa?
The basilic vein is found only in or below the AC fossa.
What is the landmark that contacts with olecranon fossa to form its joint?
The landmark that contacts with olecranon fossa to form its joint is the olecranon process of the ulna. It forms the elbow joint with the humerus at the olecranon fossa, providing stability and allowing for extension of the forearm.
What muscle originates on temporal fossa?
The temporalis originates on the temporal fossa.
Why is it named temporalis?
The temporalis muscle is named after the temporal bone of the skull to which it attaches. It originates from the temporal fossa on the side of the skull and is one of the muscles involved in chewing and closing the jaw.
Name the origin of the supraspinatus muscle?
The supraspinatus muscle originates from the supraspinous fossa of the scapula.
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.
What is an attachment site for the temporalis?
The attachment site for the temporalis muscle is the coronoid process of the mandible. This muscle originates from the temporal fossa of the skull and inserts at the coronoid process, allowing it to participate in actions like elevating and retracting the mandible during activities such as chewing and speaking.
Number of origins of the temporalis muscle?
THE ORIGIN OF THE TEMPORALIS MUSCLE IS TEMPORAL FOSSA Insertion: Coronid process of the mandible Function/Action: Closes Jaw
What bone bears the mandibular fossa?
Temporal Bone!
What muscle originates on the anterior surface of the scapula and inserts on the proximal anterior humerus?
The muscle you are referring to is the subscapularis muscle. It originates on the subscapular fossa of the scapula and inserts on the lesser tubercle of the humerus. It is responsible for medial rotation of the shoulder joint.
What is the function of the temporalis?
the function of the temporalis (muscular system) is to muscle extending from the temporal fossa to the coronoid process of the mandible; acts to raise the mandible and close the jaws.
Which portion of the temporal bone articulates with the jawbone?
at the mandibular fossa
What muscle originates in the zygomatic process?
The zygomatic process is located on the temporal bone. The process is connected to the zygomatic bone to create the zygomatic arch.
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.
