What type of ribs pairs 11-12 that connect to the vertebrae in the back but are free of any attachment in the front is known as what?
The rib pairs that attach to the back vertebrae but are not connected to the sternum are known as floating ribs. In human anatomy, the 11th and 12th rib pairs are termed floating ribs. There are 12 pairs of ribs. The floating ribs are the lowest two rib pairs that are also called false ribs.
What else can I help you with?
The first seven ribs which connect with the thoracic vertebrae your back and with the sternum in the front are?
These are called true ribs. They each have their own cartilage connection to the sternum.
The major bony components of the thorax are?
The major bony components of the thorax include the sternum, ribs, and thoracic vertebrae. The sternum, commonly known as the breastbone, is located at the front of the thoracic cavity and provides attachment for the ribs. The ribs, typically 12 pairs, curve around the sides of the thorax and protect vital organs like the heart and lungs. The thoracic vertebrae, which consist of 12 individual vertebrae, form the backbone of the thorax and provide support and flexibility to the upper body.
What is another name for the upper back vertebrae?
The upper back vertebrae are also known as the thoracic vertebrae.
Series of vertebrae forming the axis of the human skeleton?
There is only one vertebrae that is considered the axis and that is cervical vertebrae number 2 (C2). The axial skeleton is composed of the skull, facial bones, hyoid bone, the vertebrae, sacrum, and coccyx.
Tail bone vestigial fused vertebrae?
The tailbone, also known as the coccyx, is formed by the fusion of several small vertebrae that are no longer functional in humans. These fused vertebrae are considered vestigial remnants of our evolutionary history when our ancestors had tails. Today, the coccyx serves as an attachment point for muscles and has limited functional significance.
What is a another name for the back bone?
Your back bone is also known as the spine which is made up of 33 vertebrae, the sacrum, intervertebral discs, and the coccyx. There are three sections of vertebrae known as the; the cervical vertebrae (neck), the thoracic vertebrae (middle back) and the lumbar vertebrae (lower back).
What can take up residence at the end of the vertebrae column?
At the end of the vertebral column, the coccyx, commonly known as the tailbone, is located. It is composed of several fused vertebrae and serves as an attachment point for various muscles and ligaments. Additionally, in some cases, conditions like a pilonidal cyst can develop in this area, which may require medical attention.
What is lipping of vertebraes?
Lipping occurs in the vertebrae as humans age. Lipping of the vertebrae is the formation of bone between the vertebrae, commonly known as bone spurs.
What has seven components that is unfused?
The spine is composed of seven unfused vertebrae in the neck region known as the cervical spine.
Which pairs of ribs are known as floating ribs?
Lower most two pairs of ribs (11th and 12th) are known as floating ribs because they are only attached to vertebrae but not to the sternum.
Where is the vertebrae located in the lower back are the?
The vertebrae located in the lower back are known as the lumbar vertebrae. They are the five largest and strongest vertebrae in the spinal column, situated below the thoracic vertebrae and above the sacrum. The lumbar vertebrae support the majority of the body's weight and are responsible for the flexibility and movement of the lower back.
Where is the coxxyx located in the body?
The coccyx, also known as the tailbone, is located at the bottom of the vertebral column, below the sacrum. It consists of three to five fused vertebrae and serves as an attachment site for various muscles, tendons, and ligaments.
