Vertebral, disc, or muscle pain from T12-L1 may occur suddenly following an injury or develop over time. The symptoms from this motion segment are felt in the front of the abdomen and along the flank (the mid-back region and side of the abdomen – …

Apr 5, 2025 · Explore the anatomy, structure, and function of the T1 vertebra with Innerbody's interactive 3D model. The T1 vertebra is the first (uppermost) of the twelve (12) thoracic vertebrae that make up the central and largest section of the spinal column between the lumbar vertebrae below and the cervical vertebrae above.

May 4, 2022 · T1 spinal cord injury – intact sensation of the inner forearm and the ability to separate your fingers (finger abduction). T2 spinal cord injury – the uppermost chest muscles and sensation near the armpit and upper chest are intact.

Sep 14, 2012 · Some Electrical Engineers that are on here will also see : T1 = Tap 1 T2 = Tap 2 T3 = Tap 3 (of a Transformer secondary winding on the output reduced Voltage side) L1 L2 AND L3 are always used by myself for marking/tagging/labeling my 3 phase supply inputs and cable break outs/boot off's...

The lumbar spine, located between the thoracic and sacral spine, is the lower portion of the spinal cord and consists of five large, strong vertebrae labeled L1 to L5. These vertebrae are built to carry the body’s weight and support essential activities like walking, running, and lifting.

Injuries to T12 and L1 vertebra damage the lumbar cord. Injuries to L2 frequently damage the conus. Injuries below L2 usually involve the cauda equina and represent injuries to spinal roots rather than the spinal cord proper.

Jun 29, 2018 · What you need to do is to check for 24VAC at the coil terminals (usually on the side of the contactor) when the thermostat is calling for cooling. I'm guessing that you'll find that you don't have 24VAC present (that's what activates the contactor/relay to turn on the outside unit). The 24VAC comes from the house & thermostat.

Each thoracic spinal nerve is named for the vertebra above it. For example, the T3 nerve root runs between the T3 vertebra and T4 vertebra. There are 12 thoracic spinal nerve root pairs (two at each thoracic vertebral level), starting at vertebral level T1-T2 and going down to T12-L1.

Jul 16, 2023 · This series of eight guides describes outcomes according to level of spinal cord injury (C1-3, C4, C5, C6, C7-8, T1-9, T10-L1 and L2-S5).

Aug 1, 2018 · It looks to me like L1-T1 is the side that is closed on the old contactor and L3-T3 is switched, whereas on the new contactor L2-T2 is closed and L1-T1 is switched. I read elsewhere on this forum that the polarity of the low voltage wires doesn't matter.
