The L2-L3 vertebrae are located in the lower back, specifically in the lumbar region. They are the second and third vertebrae from the top of the lumbar spine, just below the L1-L2 vertebrae and above the L3-L4 vertebrae.
The second vertebrae has a dens (meaning tooth) which sticks up into the ring made by the atlas (the first vertebra). The head can pivot with this type of joint. A person can nod the head "no".
The ribs are the bones located in the posterior thorax between the second and seventh vertebrae. These ribs articulate with the thoracic vertebrae in the back and form the rib cage that helps protect vital organs in the chest cavity.
The vertebrae in the neck are called cervicle vertebrae. There are 6 of them altogether. The first two (going downward from the skull) are called the atlas and the axis. The rest are just name by their order. Eg: C1 (Atlas), C2 (Axis), C3, C4.....
When the head is moved from side to side, the first vertebra (atlas) pivots around the dens (odontoid process) of the second vertebra (axis). This motion allows for the rotation and flexibility of the neck.
second lumber vertebrae
The dens is located on the cerival vertebrae on C2, which is the second vertebrae on the cervial vertebrae.
The cervical vertebrae do not have ribs attached.
The L2-L3 vertebrae are located in the lower back, specifically in the lumbar region. They are the second and third vertebrae from the top of the lumbar spine, just below the L1-L2 vertebrae and above the L3-L4 vertebrae.
You have 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumber vertebrae, 1 sacrum and 1 coccyx. The first cervical vertebra is called as atlas vertebra. The second one is called as axis vertebra.
T1 and T2 refer to the first and second thoraxic vertebrae. They are the 8th and 9th vertebrae, starting from the top.
The second vertebrae has a dens (meaning tooth) which sticks up into the ring made by the atlas (the first vertebra). The head can pivot with this type of joint. A person can nod the head "no".
The ribs are the bones located in the posterior thorax between the second and seventh vertebrae. These ribs articulate with the thoracic vertebrae in the back and form the rib cage that helps protect vital organs in the chest cavity.
The name of the second vertebrae is called the axis.
The cervical spine is made up of seven cervical vertebrae. These are numbered(C1-C7) and are the smallest of the true vertebrae. The third through sixth cervical vertebrae have characteristics in common. The first, second, and seventh are considered special cervical vertebrae, and have different characteristics.
intervertebral discs are not found in the sacrum and coccyx, where the vertebrae have fused, or between the first and second cervical vertebrae.
The atlantoxial joint is formed by the first and second cervical vertebrae, known as the atlas (C1) and axis (C2) respectively. It allows for rotational movement of the head.
