The fourth thoracic vertebra, together with the fifth, is at the same level as the sternal angle. The thoracic spinal nerve 4 (T4) passes inferior it. A thoracic spine X-ray of a 57-year-old male. Surface orientation of T3 and T7, at middle of spine of scapula and at inferior angle of the scapula, respectively.
The bases of denticulate ligaments arise in the pia mater and are firmly attached to the arachnoid mater and dura mater at the apex. [2] The denticulate ligaments extend across the subarachnoid space between anterior nerve roots and posterior nerve roots, piercing the intervening spinal arachnoid mater to reach the dura.
This is a list of human anatomy mnemonics, categorized and alphabetized.For mnemonics in other medical specialties, see this list of medical mnemonics.Mnemonics serve as a systematic method for remembrance of functionally or systemically related items within regions of larger fields of study, such as those found in the study of specific areas of human anatomy, such as the bones in the hand ...
The vertebral canal is enclosed anteriorly by the vertebral bodies, intervertebral discs, and the posterior longitudinal ligament; it is enclosed posteriorly by the vertebral laminae and the ligamenta flava; laterally, it is incompletely enclosed by the pedicles with the interval between two adjacent pedicles on either side creating an intervertebral foramen (allowing the passage of the spinal ...
The intertransverse ligaments are weak, sheet-like [1] ligaments interconnecting adjacent transverse processes in the thoracic spine, and adjacent accessory processes in the lumbar spine. They act to limit lateral flexion and rotation of the spine.
The vertebral column, also known as the spinal column, spine or backbone, is the core part of the axial skeleton in vertebrate animals.The vertebral column is the defining and eponymous characteristic of the vertebrate endoskeleton, where the notochord (an elastic collagen-wrapped glycoprotein rod) found in all chordates has been replaced by a segmented series of mineralized irregular bones ...
The ligaments of the joint are: Costotransverse ligament [1] Lateral costotransverse ligament [1] (Anterior and posterior) superior costotransverse ligament [1] Accessory ligament - typically present. It is medial to the superior costotransverse ligament, with the dorsal ramus of a thoracic spinal nerve and associated vessels intervening ...
In the neck region the ligaments are thin, but broad and long; they are thicker in the thoracic region, and thickest in the lumbar region. They are thinnest between the atlas bone (C1) and the axis bone (C2), and may be absent in some people. They become longer inferiorly in the cervical spine, as the distance between adjacent laminae increases ...
