Clavicle
1. The clavicle, also known as the collar bone, supports the shoulder so the arm can swing freely and transmits the weight of the upper limb to the sternum.
2. It has two ends - the lateral end articulates with the acromion process to form the acromioclavicular joint, while the medial end articulates with the manubrium sterni to form the sternoclavicular joint.
3. The clavicle is the only long bone that lies horizontally and gives attachment and origin to several muscles including the deltoid, trapezius, pectoralis major, and sternocleidomastoid.
Clavicle bone Anatomy
The clavicle, or collarbone, is a modified long bone with an S-shaped curvature. It has two ends, the medial end and the lateral end. The shaft is divided into lateral one-third and medial two-thirds. The clavicle is the first bone to start ossifying and ossifies on membrane, with two primary centers of ossification. It articulates proximally with the scapula at the acromioclavicular joint and distally with the manubrium of the sternum at the sternoclavicular joint. Muscle attachments along the clavicle include the deltoid, trapezius, pectoralis major and sternocleidomastoid.
Scapula
The document describes the anatomy of the scapula bone. It notes that the scapula is a large, triangular, flat bone located on the posterolateral aspect of the chest wall opposite ribs 2-7. The dorsal surface of the scapula is divided into two portions by its spine: the supraspinous fossa superiorly and infraspinous fossa inferiorly. It describes landmarks like the superior, inferior, and lateral angles. Key borders including the lateral, medial, and superior borders and their extensions are outlined. Muscle attachments and the shoulder and acromioclavicular joints are also mentioned. Pathologies such as fractures, winging of the scapula, and scapho
Slideshow: Foot Bones
The document discusses the bones of the human foot. There are 27 bones in the foot classified into tarsal bones (7 bones including the talus, calcaneus, navicular, cuneiforms and cuboid), metatarsal bones (5 long bones) and phalanges (14 toe bones including proximal, middle and distal phalanges). The talus bone connects the foot to the lower leg and forms the ankle joint with the tibia and fibula. The subtalar joint is formed between the talus and calcaneus bones and allows for foot inversion and eversion.
anatomy..clavicle
The clavicle is a modified long bone located horizontally between the sternum and acromion process. Its medial end articulates with the manubrium to form the sternoclavicular joint and its lateral end articulates with the acromion process to form the acromioclavicular joint. It serves to support the shoulder girdle and allows the arm to swing freely from the trunk while also transmitting the weight of the upper limb through both joints.
Posterior Abdominal Wall (Anatomy of the Abdomen)
This document contains detailed anatomical descriptions and diagrams of the structures located on and passing through the posterior abdominal wall, including the abdominal aorta, inferior vena cava, common and external iliac arteries, psoas major and minor muscles, diaphragm, quadratus lumborum muscle, thoracolumbar fascia, lumbar plexus, and sympathetic chain. Each structure is labeled and their courses, branches, relations, and surface anatomy are outlined over multiple pages with annotations from Dr. Sherif Fahmy.
Slideshow: Anterior Leg
The anterior leg compartment contains four muscles - Tibialis Anterior, Extensor Digitorum Longus, Extensor Hallucis Longus, and Peroneus Tertius. These muscles dorsiflex the ankle and extend the toes, arising from the tibia and fibula and inserting at various points on the foot. They are all supplied by the deep peroneal nerve. Injury to this nerve causes foot drop.
Humerus Bone and attachments
The document describes the anatomical features of the humerus bone. It discusses the upper end, which includes the head, anatomical neck, lesser tubercle, and greater tubercle. The lower end includes the capitulum, trochlea, medial and lateral epicondyles. The shaft has borders, surfaces, and features muscle attachments from various muscles including the deltoid, pectoralis major, and triceps brachii. Ligaments like the shoulder and elbow joint capsules are also attached. Major nerves like the axillary, radial, and ulnar nerves are related to specific parts of the humerus.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
