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.
Because its cells begin in the thoracolumbar division – the thoracic and lumbar regions of the spinal cord – the sympathetic nervous system is said to have a thoracolumbar outflow. Axons of these nerves leave the spinal cord through the anterior root. They pass near the spinal (sensory) ganglion, where they enter the anterior rami of the ...
Middle back pain, also known as thoracic back pain, is back pain that is felt in the region of the thoracic vertebrae, which are between the bottom of the neck and top of the lumbar spine. It has a number of potential causes, ranging from muscle strain to collapse of a vertebra or rare serious diseases.
Brown-Séquard syndrome (also known as Brown-Séquard's hemiplegia, Brown-Séquard's paralysis, hemiparaplegic syndrome, hemiplegia et hemiparaplegia spinalis, or spinal hemiparaplegia) is caused by damage to one half of the spinal cord, i.e. hemisection of the spinal cord resulting in paralysis and loss of proprioception on the same (or ipsilateral) side as the injury or lesion, and loss of ...
The patient bends forward, as if they are diving. If the patient has scoliosis, their back often has a prominent line where the spine is, and one side is higher than the other. A patient's back is completely straight if they do not have scoliosis. The test, named after William Adams, was described in 1865.
Referred pain, also called reflective pain, [1] is pain perceived at a location other than the site of the painful stimulus.An example is the case of angina pectoris brought on by a myocardial infarction (heart attack), where pain is often felt in the left side of neck, left shoulder, and back rather than in the thorax (chest), the site of the injury.
Vertebrae of the spine, especially in the thoracic region, are, on average, asymmetric. [12] The mid-axis of these vertebral bodies tends to point systematically to the right of the median body plane. A strong asymmetry of the vertebrae and their musculature, may lead to mechanical instability of the column, especially during phases of rapid ...
The dorsal column–medial lemniscus pathway (DCML) (also known as the posterior column-medial lemniscus pathway (PCML) is the major sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (body position) from the skin and joints.
