On the lateral border of the scapula
is a shallow pyriform, articular surface, the glenoid cavity, which is directed lateralward and forward and articulates with the head of the humerus; it is broader below than above and its vertical diameter is the longest.
Where are located the acetabulum and the glenoid cavities?
The glenoid cavity is a structural feature
on the scapula bone
(also known as the shoulder blade or shoulder bone)and acetabulum is the socketof the hip bone,into which the head of the femur fits..

What is the glenoid cavity part of?
part of
scapula
…presents a shallow cavity, the glenoid cavity, which articulates with the head of the bone of the upper arm, the humerus, to form the shoulder joint. Overhanging the glenoid cavity is a beaklike projection, the coracoid process, which completes the shoulder socket.
What is glenoid cavity?
Medical Definition of glenoid cavity
:
the shallow cavity of the upper part of the scapula by which the humerus articulates with the shoulder girdle
.
Which joint is in shoulder?
The glenohumeral joint
is the one most people think of as the shoulder joint. It is formed where a ball (head) at the top of the humerus fits into a shallow cuplike socket (glenoid) in the scapula, allowing a wide range of movement.
What does glenoid mean?
Medical Definition of glenoid
1 :
having the form of a smooth shallow depression
—used chiefly of skeletal articulatory sockets. 2 : of or relating to the glenoid cavity or glenoid fossa.
What is the difference between acetabulum and glenoid cavity?
Answer: The glenoid cavity is a structural feature on the scapula bone (also known as the shoulder blade or shoulder bone)and acetabulum is the
socketof the hip bone
,into which the head of the femur fits.
Where is transverse process located in skeleton?
The transverse process is found in
the vertebral column
which is composed of vertebrae on which tiny bone-like projections are these processes. The Glenoid cavity joins the upper arm bone with the clavicle.
Is the femur in your arm?
The humerus and
the femur are corresponding bones of the arms and legs
, respectively. While their parts are similar in general, their structure has been adapted to differing functions. The head of the humerus is almost hemispherical, while that of the femur forms about two-thirds of a sphere.
What is the glenoid of the shoulder?
The head of the upper arm bone
(humeral head) rests in a shallow socket in the shoulder blade called the glenoid. The head of the upper arm bone is usually much larger than the socket, and a soft fibrous tissue rim called the labrum surrounds the socket to help stabilize the joint.
What type of shoulder dislocation is more common?
INTRODUCTION — Shoulder dislocations account for 50 percent of all major joint dislocations [1-5].
Anterior dislocation
is most common, accounting for 95 to 97 percent of cases.
What are four important muscles that help stabilize the shoulder joint?
The primary muscle group that supports the shoulder joint is the rotator cuff muscles. The four rotator cuff muscles are the
supraspinatus, infraspinatus, teres minor, and subscapularis
.
What are the three ligaments that support the shoulder joint?
Glenohumeral ligaments- Composed
of a superior, middle, and inferior ligament
, these three ligaments combine to form the glenohumeral joint capsule connecting the glenoid fossa to the humerus.
How big is the glenoid cavity?
The glenoid cavity can be described as an irregularly shaped oval, much like an inverted comma. On the basis of studies conducted by Saha, the
average height is 35 mm and the average width is 25 mm
.
What bones make up the glenoid cavity?
The shoulder is a ball and socket joint made up of three bones, namely the
humerus, scapula, and clavicle
. The end of the humerus or upper arm bone forms the ball of the shoulder joint. An irregular shallow cavity in the scapula called the glenoid cavity forms the socket for the head of the humerus to fit in.
