Nonallopathic lesions refer to conditions affecting the musculoskeletal system that are not caused by traditional diseases or trauma but may be related to dysfunctional biomechanics or stresses. The numeric codes 739.3, 739.1, and 739.5 correspond to specific anatomical locations: lumbar (lower back), cervical (neck), and pelvic regions, respectively. These classifications help healthcare providers identify and treat musculoskeletal issues that may not be directly linked to identifiable medical conditions.
pelvis
The lumbar vertebrae is a long bone
The normal anatomy of the spine is usually described by dividing up the spine into 3 major sections: the cervical, the thoracic, and the lumbar spine. (Below the lumbar spine is a bone called the sacrum, which is part of the pelvis). Each section is made up of individual bones called vertebrae. There are 7 cervical vertebrae, 12 thoracic vertebrae, and 5 lumbar vertebrae.Anatomy of the Spine
There are Five different types of Vertebrae in the Vertabral collumn (spine).1) Cervical Vertebrae (7)2) Thoracic Vertebrae (12)3) Lumbar Vertebrae (5)4) Sacral Vertebrae (5)5) Coccygeal Vertebrae (3)
The spine (also called backbone or vertebral column) starts at the top of your neck, just under the scull, and goes all the way down to your tail-bone. There are 5 regions of the spine: cervical, thoracic, lumbar, sacral, and coccygeal. However the 3 most commonly discussed regions are the cervical, thoracic, lumbar regions. The cervical region is in the neck. The thoracic region is in the upper to mid back. The lumbar region is in the low back. The sacral region is in the back of your pelvis, between your buttocks. Finally, the coccygeal region is your "tail-bone."
Lumbar-pelvic dissociation refers to the independent movement of the lumbar spine (lower back) and the pelvis. This separation of movement is important for functional activities such as walking, running, and bending at the waist. Insufficient lumbar-pelvic dissociation can lead to compensatory movements and potential risk for injury.
The lumbar enlargement is a region of the spinal cord that exhibits a widening in the lower back area. It serves as the main site for the spinal nerves that innervate the lower limbs. This enlargement is responsible for the increased nerve activity associated with controlling and coordinating movements of the legs and pelvis.
An adult human skeleton typically has 33 vertebrae, including 7 cervical (neck), 12 thoracic (mid-back), 5 lumbar (lower back), 5 sacral (fused into one bone, part of the pelvis), and 4 coccygeal (tailbone) vertebrae.
The "lumbar" is not actually a part of the body - it is an adjective referring to the area around the lower spine. For example, the lumbar vertebrae are a set of five bones below the diaphragm and above the pelvis.
The spine is divided into five regions: cervical (neck), thoracic (upper back), lumbar (lower back), sacrum, and coccyx (tailbone). Each region plays a specific role in supporting the body and protecting the spinal cord. The cervical spine provides flexibility for head movement, the thoracic spine protects the vital organs, the lumbar spine supports body weight, the sacrum connects the spine to the pelvis, and the coccyx helps with sitting and balance. Maintaining the health and alignment of these regions is crucial for overall spinal function and preventing issues like pain and injury.
The vertebrae. There are 7 in the neck (cervical), 12 in the thorax (chest), and 5 in the lower back (lumbar). The wedge shaped bone in the back of the pelvis (the sacrum) is composed of 5 fused vertebrae and the the coccyx (or "tail bone") has 3-5 vertebrae.
The connection is made with ligaments and connective tissues. Below the lumbar spine is the sacrum. The sacrum is actually a group of specialized fused vertebrae that connects the spine to the pelvis.
