🦴 Introduction to Clavicle Anatomy
This paragraph introduces the topic of clavicle anatomy, highlighting that the clavicle consists of two parts (right and left). It is located subcutaneously, making it easily palpable. The shape of the clavicle resembles an 'S,' with the anterior part convex and the lateral half concave. The description sets the foundation for a deeper dive into the clavicle's anatomical structure.
🔍 Key Anatomical Features of the Clavicle
This section discusses the key anatomical structures of the clavicle. The clavicle has two extremities: the medial end called 'extremitas sternalis,' which articulates with the manubrium sterni, and the lateral end called 'extremitas acromialis,' which connects with the acromion of the scapula. The paragraph provides a clear distinction between these two extremities and their respective articulations.
🧩 Clavicle Joint Surfaces and Articular Facets
This part elaborates on the articular facets at the ends of the clavicle. The extremitas acromialis has a 'facies articularis acromialis' that connects with the scapula, while the extremitas sternalis has a 'facies articularis sternalis,' which interacts with the manubrium sterni. These articular surfaces are critical for the clavicle’s connection to the surrounding skeletal structures.
🦵 Ligament Attachments on the Clavicle
The paragraph highlights the ligaments attached to the clavicle, focusing on two key points. First, the 'tuberculum conoideum,' which serves as the attachment for the conoid ligament (connecting the clavicle to the scapula's coracoid process). Second, the 'linea trapezoidea,' which serves as an attachment for the trapezoid ligament. Both ligaments play crucial roles in the stability of the clavicle and its articulation with the scapula.
🔗 Muscle and Ligament Attachments
The discussion here extends to more ligament and muscle attachments, particularly the 'sulcus musculi subclavii,' which is the insertion point for the subclavius muscle. Another important feature is the 'tuberositas costalis,' which serves as an attachment for the costoclavicular ligament, linking the clavicle to the first rib (Os Costae). This provides stability between the clavicle and the ribcage.
⚖️ Clavicle's Costal Tuberosity and Exam Details
This section concludes by emphasizing the importance of distinguishing the 'tuberositas costalis' of the clavicle in examinations. It also introduces the term 'impressio ligamenti costoclavicularis,' which refers to the area where the costoclavicular ligament attaches. The description reinforces the need to properly identify and label the tuberosity in medical exams to avoid confusion with other skeletal structures.

Highlights
Discussion begins on clavicle anatomy, specifying two clavicles on the right and left side.
Clavicle is located in the subcutaneous layer, making it palpable and easily identified.
The clavicle is situated above the T1 vertebra and has an S-shaped curve.
The medial part of the clavicle is convex, and the lateral part is concave.
Explanation of the anatomical structure of the clavicle, focusing on two main ends: the sternal and acromial extremities.
The sternal extremity articulates with the manubrium sterni, forming the sternoclavicular joint.
The acromial extremity articulates with the acromion of the scapula, forming the acromioclavicular joint.
The clavicle features articular surfaces at both extremities, including the facies articularis acromialis and facies articularis sternalis.
Clavicle contains several bony projections, such as the conoid tubercle, which serves as an attachment site for the coracoclavicular ligament.
The conoid ligament connects the coracoid process of the scapula with the clavicle.
Another notable structure is the trapezoid line, which serves as an attachment point for the trapezoid ligament.
The trapezoid ligament also connects the clavicle to the coracoid process of the scapula.
The clavicle's subclavian groove serves as an insertion point for the subclavius muscle.
Mention of the costal tuberosity (tuberositas costalis), located on the inferior surface of the clavicle.
The costal tuberosity is the attachment point for the costoclavicular ligament, which connects the clavicle to the first rib.

adalah ekstremitas yang pertama Disini
yang bagian medial ini adalah
ekstremitas sternalis karena dia
Hai dikuasi dengan manubrium sterni kaos
dan mug
kemudian ekstremitas yang satunya itu
adalah ekstremitas acromialis yang
bagian sini ya di karena dia
berartikulasi dengan
proses
Akrom Young OST skapula Oke kita lihat
struktur anatomis nya Nah ini tandiyah
Ini namanya ekstremitas acromialis ini
ekstremitas sternalis
masing-masing ekstremitas ini di
ujungnya itu ada fasilitasnya facies
articularis nya atau fat fast yang
Hai membentuk persendiannya
Hai Nah di sini ada facies articularis
acromialis yah ini Kemudian pada bagian
medianya ada facies articularis teroris

tuberositas costalis nah disini saya
cuma tuberositas costalis ya tetapi
kalau dalam ujian kalian enggak bisa
cuma tulis tuberositas costalis tetapi
harus tuberositas costalis house
