Odontoid process
Also known as the dens.
What is the uppermost part of the sternum called?
Manubrium
It articulates with the clavicles and the first rib.
What is the body of the sternum referred to as?
Gladiolus
It is the longest part of the sternum.
What is the name of the lower part of the sternum?
Xiphoid process
It is a small, cartilaginous structure.
What are the ribs that directly attach to the sternum called?
Vertebrosternal ribs
Also known as true ribs.
What are the ribs that do not directly attach to the sternum but connect through cartilage called?
Vertebrochrondral ribs
Also known as false ribs.
What are the two girdles in the human skeleton?
Pelvic girdle and Pectoral girdle
They connect the limbs to the axial skeleton.
What bone is known as the collarbone?
Clavicle
It connects the arm to the body.
What is the name of the cavity that receives the head of the humerus?
Glenoid fossa
It is part of the scapula.
What fossa is located above the spine of the scapula?
Supraspinous fossa
It serves as an attachment for muscles.
What fossa is located below the spine of the scapula?
Infraspinous fossa
It also serves as an attachment for muscles.
What is the fossa on the scapula where the subscapularis muscle attaches?
Subscapular fossa
It is located on the anterior surface of the scapula.
What is the bony prominence on the scapula that forms the highest point of the shoulder?
Acromion process
It articulates with the clavicle.
What is the small, hook-like structure on the scapula called?
Coracoid process
It serves as an attachment point for muscles and ligaments.
What are the larger and smaller projections on the proximal end of the humerus called?
Greater and Lesser tubercles
They provide attachment points for muscles.
What is the groove located between the greater and lesser tubercles of the humerus?
Intertubercular groove
It houses the tendon of the biceps brachii.
What are the bony projections on either side of the elbow joint called?
Epicondyles
They provide attachment for forearm muscles.
What is the depression on the humerus that accommodates the olecranon of the ulna?
Olecranon fossa
It is located on the posterior aspect of the humerus.
What is the notch on the ulna that articulates with the humerus?
Trochlear notch
It allows for flexion and extension of the elbow.
What is the prominent bony structure at the proximal end of the ulna called?
Olecranon process
It forms the elbow’s point.
What is the notch on the ulna that receives the head of the radius?
Radial notch
It is part of the ulna.
What is the bony prominence on the radius where the biceps tendon attaches?
Radial tuberosity
It is located just below the neck of the radius.
What is the small bony projection at the distal end of the radius called?
Styloid process
It provides attachment for ligaments of the wrist.
What is the name of the bone in the wrist that is boat-shaped?
Scaphoid
It is one of the carpal bones.
What is the name of the carpal bone that is moon-shaped?
Lunate
It articulates with the radius.
