What vertebrae are in the chest?
What vertebrae are in the chest?
The thoracic cage (rib cage) forms the thorax (chest) portion of the body. It consists of the 12 pairs of ribs with their costal cartilages and the sternum ((Figure)). The ribs are anchored posteriorly to the 12 thoracic vertebrae (T1–T12). The thoracic cage protects the heart and lungs.
Which section of vertebrae is in the chest area?
The remaining small bones or ossicles below the sacrum are also fused together and called the tailbone or coccyx. The spine above the sacrum consists of: Seven bones in the neck—the cervical spine. 12 bones in the chest—the thoracic spine.
What spinal nerves affect the chest?
T-1 through T-5 nerves affect muscles, upper chest, mid-back and abdominal muscles. These nerves and muscles help control the rib cage, lungs, diaphragm and muscles that help you breathe. T-6 through T-12 nerves affect abdominal and back muscles.
What is the name for the vertebrae bones at the chest level?
The thoracic section of the spine is located at chest level, between the cervical and lumbar vertebrae. The vertebrae in this section are labeled T1 to T12 and serve as attachments for the rib cage. The lumbar section is located between the thoracic vertebrae and the sacrum.
What is your upper chest called?
The pectoralis major extends across the upper part of the chest and is attached to a ridge at the rear of the humerus (the bone of the upper arm). Its major actions are adduction, or depression, of the arm (in opposition to the action of the deltoideus muscle) and rotation of the arm forward about the axis of the body.
Which group of spinal vertebrae is closest to the chest?
The numbers 1 to 7 indicate the level of the vertebrae. C1 is closest to the skull, while C7 is closest to the chest.
Can spine problems cause chest pain?
Your spine is a prevalent cause of chest pain. Treating your thoracic spine and rib cage is usually the solution. However, chest pain originating from your spine won’t kill you, but a heart attack can! Spinal Discs can refer to pain through your chest wall like a knitting needle.
Can a pinched nerve affect your chest?
A pinched nerve in the cervical spine can give you a stiff neck, and the pain and numbness can affect the shoulder and arm. A pinched lumbar nerve in the lower back can cause pain in your back, hips, buttocks and legs. Thoracic radiculopathy causes pain in your chest area.
What are the 5 types of vertebrae?
Vertebrae. As mentioned above, our vertebrae are numbered and divided into five regions: cervical, thoracic, lumbar, sacrum, and coccyx.
What organs are in your upper chest?
The chest is the area of origin for many of the body’s systems as it houses organs such as the heart, esophagus, trachea, lungs, and thoracic diaphragm. The circulatory system does most of its work inside the chest.
What is the largest muscle in the chest?
The pectoralis major is the superior most and largest muscle of the anterior chest wall.
Which vertebrae is most important?
Lumbar Spine: In your low back, you have 5 vertebrae that are labeled L1 to L5 (the ‘L’ means lumbar). Some people have 6 lumbar vertebrae. These vertebrae are your largest and strongest vertebrae, responsible for carrying a lot of your body’s weight.
How is thoracic back pain treated?
Because pain in the thoracic region is often caused by muscle tension and poor posture, initial treatment efforts focus on relieving the tension with stretching, massage, and over-the-counter medications such as acetaminophen or ibuprofen. Heat and/or ice therapy can help reduce muscle pain and stiffness as well.
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. The thoracic spine (highlighted) spans the upper and mid-back.
What is the name of the top vertebrae in your spine?
The cervical is the upper part of the spine, made up of seven vertebrae (bones). The thoracic is the center portion of the spine, consisting of 12 vertebrae. The lower portion of the spine is called the lumbar spine. It is usually made up of five vertebrae, however, some people may have six lumbar vertebrae.
Your spine is a prevalent cause of chest pain. However, chest pain originating from your spine won’t kill you, but a heart attack can! Treating your thoracic spine and rib cage is usually the solution for non-cardiac conditions. Spinal Discs can refer to pain through your chest wall like a knitting needle.
What does thoracic nerve pain feel like?
Individuals with a thoracic pinched nerve often experience some of the following symptoms: Pain in the middle of the back. Pain that radiates to the front of the chest or shoulder. Numbness or tingling that extends from the back into the upper chest.
Which is the most prominent of the thoracic vertebrae?
First thoracic vertebra T1 25% of the time it is the most prominent, it does not rotate as much as C7 when the head turns. Throat landmarks Hyoid C3 level, Thyroid cartilage C4-5, First cricoid ring C6 Thoracic spine landmarks Second thoracic vertebra T2 superior angle of scapula. Sixth and seventh thoracic vertebrae
How is the thoracic cavity related to the rib cage?
Thoracic Cavity Definition. The thoracic cavity, also called the chest cavity, is a cavity of vertebrates bounded by the rib cage on the sides and top, and the diaphragm on the bottom. The chest cavity is bound by the thoracic vertebrae, which connect to the ribs that surround the cavity.
What are the main organs in the chest cavity?
The thorax includes the thoracic cavity and the thoracic wall. It contains organs including the heart, lungs, and thymus gland, as well as muscles and various other internal structures. Many diseases may affect the chest, and one of the most common symptoms is chest pain.
Where are the landmarks of the lumbar vertebra?
Lumbar spine landmarks Fourth lumbar vertebra L4 spinous is at the level of iliac crests. This is an extremely useful landmark. You can find the iliac crests by placing the sides of your forefinger/hand in the fleshy part of the waist at the level of the umbilicus. Move inferiorly and the first hard lumps you feel on each side are the iliac crests.
Where does the pain in the chest come from?
While most heart and chest pain occur in the area behind the breastbone, cardiac pain may also radiate down your arms, back, shoulders, and neck. Chest pain related to the heart is also described differently.

Where are the thoracic spinal nerves located in the body?
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. T9, T10, T11, and T12 can feed into the abdomen and/or lower in the back. 1
Where does enthesitis cause pain in the chest?
The costo-sternal joints link the ribs to the breastbone. This is a common site of enthesitis and is often associated with tenderness (red areas). The ligament and tendon insertions of the collar bone also join the breast bone and this can result in anterior chest wall pain.
