What is the function of the bone markings illustrated on this rib: head and facets? Surfaces that form joints; Heads and facets are both terms used to indicate a joint surface. Many bones of the skeleton have heads, which commonly articulate with fossae; facets are smooth, flat joint surfaces that form plane joints.

Where is the greater tubercle?The greater tuberosity is the prominent area of bone at the top of the humerus and is the attachment for the two large, powerful rotator cuff muscles – supraspinatus and infraspinatus. It is injured/fractured in a fall by either landing directly onto the side of your shoulder or landing with your arm outstretched.
Article first time published onWhat is the difference between trochanter and tubercle?
is that trochanter is (anatomy) in vertebrates with legs, the end of the femur near the hip joint, not including the head or neck while tubercle is (anatomy) a round nodule, small eminence, or warty outgrowth, especially those found on bones for the attachment of a muscle or ligament or small elevations on the surface …
What are bone markings and why are they important?
Bone markings are projections and depressions found on bones, which help us to identify the location of other body structures, such as muscles. Their importance comes when we try to describe the shape of the bone or to understand how the muscles, ligaments and other structures affect this bone and vice versa.
What is the difference between the tubercle and tuberosity?
The main difference between tuberosity and tubercle is that tuberosity refers to a slightly larger lump on bones, but tubercle refers to the smaller lump. Some of the examples of tuberosity are the greater tuberosity of the humerus and the ischial tuberosity of the hip bone.
What is the greater tubercle?
Greater tubercle – this is the attachment site for three of the four rotator cuff muscles. It’s a bony knob on the humeral head that sits a little bit posterior (behind) and lateral (away from the midline) to its counterpart, the lesser tubercle.
Which tubercle is medial?
The lesser tubercle of the humerus, although smaller, is more prominent than the greater tubercle: it is situated in front, and is directed medially and anteriorly.
What is the crest of greater tubercle?
English: The crest of the greater tubercle forms the lateral lip of the bicipital groove and is the site for insertion of pectoralis major and the crest of the lesser tubercle forms the medial lip of the bicipital groove and is the site for insertion of teres major and latissimus dorsi muscles.
Where is the pubic tubercle?
The pubic tubercle is a prominent forward-projecting tubercle on the upper border of the medial portion of the superior ramus of the pubis bone. The inguinal ligament attaches to it. Part of the abdominal external oblique muscle inserts onto it.
Where is tubercle of rib?
On the posterior surface at the junction of the neck and body of the rib, and nearer the lower than the upper border, is an eminence—the tubercle; it consists of an articular and a non-articular portion.
Which part of a thoracic vertebra does a rib tubercle articulate with?
The rib tubercle articulates with the transverse process of a thoracic vertebra. The angle is the area of greatest rib curvature and forms the largest portion of the thoracic cage. The body (shaft) of a rib extends anteriorly and terminates at the attachment to its costal cartilage.
What are the functions of bone markings name two specific examples?
Bone markings are very important since they allow for identification of bones and bony pieces, enable joints to form, enable bones to slide past each other, enable bones to lock in place, and provide places for muscle and connective tissues to attach and provide structural support.
What is a groove bone marking?
Groove – A furrow in the bone surface that runs along the length of a vessel or nerve, providing space to avoid compression by adjacent muscle or external forces. Examples include a radial groove and the groove for the transverse sinus. Head – A rounded, prominent extension of bone that forms part of a joint.
What is a tubercle skin lesion?

Which view of the shoulder shows the greater tubercle in profile?
Diagram of the external rotation humerus view of the shoulder. The red arrow points to the greater tubercle of the humerus in profile. The red shaded oval is the overlap between the humeral head and the glenoid.
Which muscle inserts on the greater tubercle of the humerus?
Supraspinatus muscle The supraspinatus muscle has its origin in the supraspinatous fossa and inserts on the greater tubercle of the humerus – similar to the teres minor muscle.
Does Infraspinatus abduct?
Infraspinatus is the main external rotator of the shoulder joint. It assists in producing shoulder extension. With the arm fixed, it abducts the inferior angle of the scapula.
Where is the condyle?
A condyle (/ˈkɒndəl/ or /ˈkɒndaɪl/; Latin: condylus, from Greek: kondylos; κόνδυλος knuckle) is the round prominence at the end of a bone, most often part of a joint – an articulation with another bone. It is one of the markings or features of bones, and can refer to: On the femur, in the knee joint: Medial condyle.
