What is the difference between tubercle and tuberosity?
Tuberosity - A moderate prominence where muscles and connective tissues attach. ... Tubercle - A small, rounded prominence where connective tissues attach. Examples include the greater and lesser tubercle of the humerus.
What is a tubercle on a bone?
A tubercle is a small rounded point of a bone. It also refers to a nodule attached to bone, mucous membrane (moist layer lining parts of the body), or skin.
What is the purpose of a tuberosity on a bone?
In the human skeleton and that of at least other mammals, a tubercle, tuberosity or apophysis is a protrusion or eminence that serves as an attachment for skeletal muscles. The muscles attach by tendons, where the enthesis is the connective tissue between the tendon and bone.
What is the greater tuberosity of the humerus?
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.
What is the meaning of tuberosity?
: a rounded prominence especially : a large prominence on a bone usually serving for the attachment of muscles or ligaments.
Where is the tuberosity bone located?
The ischial tuberosity is a rounded bone that extends from the ischium — the curved bone that makes up the bottom of your pelvis. It's located just below the ischial spine, which is a pointed bone that extends up the backside of your pelvis.
Where is the greater tubercle of the humerus located?
The greater tubercle is located laterally on the humerus and has anterior and posterior surfaces. It serves as an attachment site for three of the rotator cuff muscles – supraspinatus, infraspinatus and teres minor – they attach to superior, middle and inferior facets (respectively) on the greater tubercle.
Is a fissure a depression or opening?
Complete list of bone markings
| Parts of a bone | Head (epiphysis) Neck (metaphysis) Body (diaphysis) Articular surface |
|---|---|
| Openings and depressions | Foramen and fissure Meatus Fossa and fovea Incisure and sulcus Sinus |
What are the major bone markings?
There are three general classes of bone markings: (1) articulations, (2) projections, and (3) holes. As the name implies, an articulation is where two bone surfaces come together (articulus = “joint”).
What is tuberosity fracture?
Tuberosity avulsion or fracture may occur after a fall onto an outstretched upper extremity due to an eccentric load applied by the attached rotator cuff on the tuberosity, often in the setting of a traumatic glenohumeral dislocation.
What is maxillary tuberosity?
The maxillary tuberosity is the most hind-most (distal) aspect of the upper jaw (maxilla), housing the. sockets of the upper wisdom teeth, with its back (posterior) border curving upward and distally.
Is the deltoid tuberosity medial or lateral?
In human anatomy, the deltoid tuberosity is a rough, triangular area on the anterolateral (front-side) surface of the middle of the humerus to which the deltoid muscle attaches.
