What nerves are affected by T1 and T2?

What nerves are affected by T1 and T2?


  • T1 and T2 (top two thoracic nerves) feed into nerves that go into the top of the chest as well as into the arm and hand.
  • T3, T4, and T5 feed into the chest wall and aid in breathing.
  • T6, T7, and T8 can feed into the chest and/or down into the abdomen.

What affects T1 T2?

T1-T2 Pinched Nerve: The T1 spinal nerve is responsible for the ring and pinky fingers and the area at the first rib. A pinched nerve may cause pain in the back or chest at the first rib, or pain in the ring and/or pinky fingers.

Where is T1 and T2 in the spine?

The thoracic vertebrae T1 is located in the upper part of the back. It’s the first section of the thoracic vertebrae, so it is located between the seventh cervical vertebra (C7) and T2.

What does T1 nerve control?

The thoracic spine has 12 nerve roots (T1 to T12) on each side of the spine that branch from the spinal cord and control motor and sensory signals mostly for the upper back, chest, and abdomen.

What does the T2 nerve control?

The nerves in the area of a vertebra control specific parts of the body. For example, the 7th cervical nerve (C7) in the neck area controls the triceps (the muscle in the upper arm), while the thoracic nerves (T2 through T7) control the chest muscles.

Can an MRI miss a pinched nerve?

An MRI may show nerve entrapment, but it has limitations. It only shows narrowing when the MRI was taken, at one point in time. It cannot tell if the nerve was more severely pinched three weeks ago or how tightly the nerve is being pinched right now.

What nerves are affected by T1?

T1 motor root innervates the flexor digitorum superficialis, flexor pollicis longus, flexor pollicis longus, flexor digitorum profundus, lumbricals, interossei, and the pectoralis major. Differentiating motor function from the C8-T1 nerve roots and ulnar nerve pathology can be assessed with motor testing.

Why does my T1 hurt?

A vertebral, rib, and/or disc injury at the C7-T1 level may cause moderate to severe neck pain and/or upper back pain. Sometimes, there may be difficulty in breathing if the first rib or rib muscles are injured.

What muscles are innervated by T1?

Spinal root T1 innervates primarily forearm and hand muscles. These are: Flexor digitorum superficialis, Flexor policis longus, Flexor digitorum profundus, Lumbricals, and Interossei. However, it also innervates Pectoralis major.

What nerves are affected by T2?

The thoracic spinal nerve 2 moves underneath the T2. The spinal nerve consists of different nerves moving along the spinal column. The nerves control sensory and motor signals from the spinal column to the body, enabling the body react to the movement of the spine.

Can an MRI scan show nerve damage?

An MRI may be able help identify structural lesions that may be pressing against the nerve so the problem can be corrected before permanent nerve damage occurs. Nerve damage can usually be diagnosed based on a neurological examination and can be correlated by MRI scan findings.

Can a disc herniation occur at the T1 level?

Symptomatic disc herniation in the upper thoracic spine from T1 to T4 is rare, with most occurring at T1–T2 levels [ 3 , 6 , 19 , 28 , 30 , 34 ] [ Table 1 ].

What does herniated disc C7-T1 stand for?

Herniated Disc C7-T1 A herniated disc C7-T1 is a fairly common place to experience a bulging disc and considerable deterioration of the overall intervertebral structure. This area marks the frontier between the cervical spine and the thoracic spine and is actually a strong and resilient intervertebral level.

Who are the authors of T2 disc herniation?

T1–T2 disc herniation: Report of four cases and review of the literature. 24-Apr-2019;10:56 How to cite this URL: Abolfazl Rahimizadeh, Amir Hossein Zohrevand, Nima Mohseni Kabir, Naser Asgari. T1–T2 disc herniation: Report of four cases and review of the literature. 24-Apr-2019;10:56.

What happens if you have a herniated thoracic disc?

In serious cases, a thoracic herniated disc can lead to paralysis from the waist down. Lateral disc herniation. When herniating laterally, or to the side, the thoracic herniated disc is more likely to impinge on the exiting nerve root at that level of the spine and cause radiating chest wall or abdominal pain. Centro-lateral disc herniation.

When do I need surgery for a herniated disk?

Surgery for a herniated disk would be considered if there is nerve damage, if pain and other symptoms are so severe that they interfere with daily activities, or if non-surgical treatment is not effective. Surgery often can resolve herniated disk symptoms more quickly than other treatments.

What is the prognosis for a herniated disc?

Most back and leg pain will get better gradually – usually within six weeks – by taking simple measures. In fact, most people with herniated disks respond to conservative treatment within six weeks and are able to return to their normal activities. Some will continue to have back pain even after treatment.

Is a herniated disc and pinched nerve the same thing?

While these terms are widely used, technically, a pinched nerve is not the same as a herniated disc. It is in fact the result of a herniation, which causes the nerve to become pinched. It is therefore important to distinguish the two, in order for the doctor to locate the actual source of the pain and to treat it properly.

What exactly is a herniated disc?

A herniated disk is a condition when the spinal disks ruptures, and a portion of the spinal disc pushes outside its normal boundary. When a herniated disc occurs, the soft interior of the disk bulges goes out and places pressure on the nearby nerves of the spinal. cord.
