What is the spinal column?

What is the spinal column?

The bones, muscles, tendons, and other tissues that reach from the base of the skull to the tailbone. The spinal column encloses the spinal cord and the fluid surrounding the spinal cord. Also called backbone, spine, and vertebral column.

What part of the body is the spinal column?

The spinal cord is an extension of the central nervous system (CNS), which consists of the brain and spinal cord. The spinal cord begins at the bottom of the brain stem (at the area called the medulla oblongata) and ends in the lower back, as it tapers to form a cone called the conus medullaris.

Where is the column located in the human body?

The Spinal Column is also called the vertebral column. The bones in the spine are called vertebrae (ver-ta-bray). The column starts at the base of the skull and continues to the pelvis.

What is the bones at the back of vertebral column?

The bottom of the spine is called the sacrum. It is made up of several vertebral bodies usually fused together as one. The remaining small bones or ossicles below the sacrum are also fused together and called the tailbone or coccyx.

How many spinal columns are in the human body?

Vertebrae. Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig.

What are the 5 areas of the spine?

The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.

How many bones are in the vertebral column quizlet?

The Skeleton: Vertebral Column (26 bones) Flashcards | Quizlet.

Which position puts the least pressure on the spine?

And while it may seem a bit counterintuitive, sitting down to “take a load off” can actually add quite a bit of pressure to our backs. When our back is in its ideal position, with us standing straight up or lying flat, we’re placing the least amount of pressure on the discs between vertebrae.

What part of the spine controls the heart?

Thoracic (mid back) – the main function of the thoracic spine is to hold the rib cage and protect the heart and lungs. The twelve thoracic vertebrae are numbered T1 to T12.

What absorbs shock in the spine?

The intervertebral discs are soft structures which act as shock absorbers between each of the vertebrae (bones) in the spine. A single disc sits between each vertebra.

Where is the vertebral column located on the body?

It is the surface of the body opposite from the chest and the abdomen. The vertebral column runs the length of the back and creates a central area of recession.

Which is the building block of the spinal column?

The individual bones of the spine are the vertebrae. These are the building blocks of the spinal column. The vertebrae protect and support the spinal cord. They also bear the majority of the weight put upon your spine.

Where are the back muscles located in the body?

The back is the body region between the neck and the gluteal regions. It comprises the vertebral column (spine) and two compartments of back muscles; extrinsic and intrinsic. The back functions are many, such as to house and protect the spinal cord, hold the body and head upright, and adjust the movements of the upper and lower limbs .

Which is the central feature of the human back?

The central feature of the human back is the vertebral column, specifically the length from the top of the thoracic vertebrae to the bottom of the lumbar vertebrae, which houses the spinal cord in its spinal canal, and which generally has some curvature that gives shape to the back.
