The Human Skeletal System
The human skeletal system consists of 206 bones that provide structure, protect organs, allow muscle attachment, store minerals, and produce red blood cells. Bones can be divided into the axial skeleton of the skull, spine, and rib cage and the appendicular skeleton of the arms, shoulders, and legs. Bones are also classified by shape as long bones like the femur and phalanges, short bones like the carpals and patella, flat bones, or irregularly shaped bones.
Ch 5 skeletal system
The skeletal system includes bones, joints, cartilage, and ligaments. It is divided into the axial skeleton which includes the skull, ribs, and vertebrae, and the appendicular skeleton which includes the pelvis and extremities. Bones provide structure, protection, movement, storage, and blood cell formation. There are 206 bones in the adult skeleton which are classified by shape as long, short, flat, or irregular. Bones are made of compact and spongy bone tissue and contain bone cells. The skeletal system allows for movement through articulations between bones.

It is composed of 206 bones in adults and consists of two main parts: the axial skeleton with 80 bones including the skull, ribs, and vertebral column, and the appendicular skeleton with 126 bones including the pectoral girdle, forelimbs, pelvic girdle and hindlimbs. The skeletal system works with muscles to provide structure and movement to the body.
Skeletal System of Human Body
Joints connect bones and allow movement. There are several types of joints including fibrous joints made of collagen, cartilaginous joints made of cartilage, gliding joints which allow bones to glide against each other, hinge joints which allow bending in one direction, and ball and socket joints which allow a full range of motion. Bones also contain bone marrow which can be yellow and contain fat or red and produce blood cells. Some diseases that affect the skeletal system include bursitis which causes inflammation around joints, tendonitis which inflames tendons, carpal tunnel syndrome affecting the wrist, osteoporosis which weakens bones, and cancers like leukemia and myeloma which affect the bone marrow.
Skeletal System
The document summarizes key topics related to the skeletal system and bone structure and function:
- Bones provide structural support, protection of organs, leverage for muscle attachment, storage of minerals, and production of blood cells.
- Long bones have a diaphysis, epiphyses, periosteum, endosteum, and contain compact or cancellous bone.
- Bones are remodeled throughout life by osteoblasts which build bone and osteoclasts which resorb bone.
- Bones grow in length via the epiphyseal plate until closure in early adulthood. Nutrition, hormones, and mechanical stresses influence bone growth and remodeling.
Skeletal System
The skeletal system provides structure and protection to the body. It maintains the body's shape and allows for movement through joints and leverage of muscles. The skeletal system also stores minerals and produces blood cells. Bones are composed of compact bone and spongy bone, and are continually remodeled through the actions of osteoblasts, osteocytes, and osteoclasts.

Congenital Anomalies Of Spine And Spinal Cord
This document discusses various congenital spinal anomalies seen on imaging. It begins by describing common congenital lesions of the spine like spinal dysraphism and caudal spinal anomalies. It then discusses various imaging modalities used to evaluate these lesions such as MRI, plain radiography, and ultrasound. The document then summarizes stages of spinal cord development and provides diagrams to illustrate gastrulation, primary neurulation, and secondary neurulation. It classifies spinal dysraphisms into open and closed types and describes specific lesions under each type. It concludes by discussing complex closed spinal dysraphisms involving disorders of midline notochordal integration and notochordal formation.
Kyphosis lordosis
The document discusses different types of spinal curvature abnormalities including kyphosis, lordosis, and scoliosis. It defines each condition and describes their causes, symptoms, diagnostic tests, and treatment options. There are three main types of kyphosis - postural, Scheuermann's, and congenital. Lordosis is an inward curvature of the lumbar or cervical spine that can be caused by factors like poor posture or congenital abnormalities. Scoliosis is a lateral curvature of the spine that can be idiopathic, congenital, or neuromuscular in origin. Treatment depends on the underlying cause but may include exercises, bracing, or corrective surgery.
Degenerative spine
Degenerative spine disease involves three main areas: the intervertebral disc, vertebral bodies/end plates, and posterior elements. Changes to the intervertebral disc include decreased water/proteoglycan content leading to distorted collagen fibers and tears in the annulus fibrosis. Vertebral endplates can show three stages of degeneration. Posterior element changes include facet joint osteoarthritis with osteophytes/hypertrophy, ligamentum flavum hypertrophy/cysts, and spinal canal/foraminal stenosis. Imaging plays an important role in evaluating these degenerative changes and their effects.

Skeletal System 1
The skeletal system is composed of bones and connective tissues that provide structure, support, protection, movement, and mineral storage. There are four main bone types - long bones in the limbs, short bones in the wrists and ankles, flat bones in the skull and trunk, and irregular bones like the vertebrae. Bones have external features like ridges and internal structures like compact and spongy bone. The spinal column consists of 33 vertebrae that are specialized in different regions and enable movement while protecting the spinal cord.

The nervous system is divided into the central nervous system and the peripheral nervous system. The central nervous system includes the brain and spinal cord, and controls and coordinates body functions. The peripheral nervous system connects the central nervous system to the rest of the body using nerves and contains sensory neurons that carry messages to the central nervous system and motor neurons that carry messages away from it. Neurons are the basic functional units of the nervous system and communicate with each other via electrical and chemical signals to control bodily functions like movement and organ activity.
Chapter 22 Muscular System
The muscular system is composed of muscle fibers that are of varying lengths and shapes and form muscles, making up 42% of total body weight. Muscles contract and allow for movement, maintain posture and temperature, and provide stability by holding bones together. There are three types of muscle tissue: skeletal muscle which is voluntary and attached to bones, smooth muscle which is involuntary and found in internal organs, and cardiac muscle which is striated and involuntary, found only in the heart. The development and strength of muscles changes throughout the lifespan from growth and development in children to declines in mobility and muscle properties in older adults.

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.
