The mammillary process is a superior process on costal process connected in the lumbar region with the back part of the superior articular process.
What is the function of Mammillary process?
The primary function associated with the mammillary bodies is recollective memory. Memory information begins within the hippocampus. Theta waves activate CA3 neurons in the hippocampus.
Where is the mammillary process?
The mamillary processes are located between transverse and cranial articular process on thoracic and lumbar vertebrae.
What is mammillary process of lumbar vertebra?
[TA] a small apophysis or tubercle on the dorsal margin of the superior articular process of each of the lumbar vertebrae and usually of the twelfth thoracic vertebra.
What does the mammillary process attach to?
Mammillary processes can be found on the posterior surface of each superior articular process. They act as sites of attachment for deep back muscles.
What are the mammillary bodies and why are they important?
Mammillary bodies, and their projections to the anterior thalamus via the mammillothalamic tract, are important for recollective memory. The medial mammillary nucleus is mainly responsible for the spatial memory deficits that are seen in rats with mammillary body lesions.
What is an accessory process?
Anatomical Parts The accessory process is an inferior tubercle of the lower thoracic vertebrae situated at the back part of the base of the costal process, rudiment of the original transverse process.
Which vertebrae have Mammillary processes?
Lumbar vertebrae have mammillary bodies on the superior articular processes not present in thoracic vertebrae. This study observed that TLTV have irregular mammillary bodies present in both the thoracic and lumbar regions.
What attaches to the accessory process?
It gives attachment to the multifidus and to the medial intertransverse muscle. The accessory process varies in prominence and may be difficult to identify. It gives attachment to the medial intertransverse muscle. The costal element is incorporated in the transverse process (fig.
What is intervertebral foramen?
Abstract. The intervertebral foramen serves as the doorway between the spinal canal and periphery. It lies between the pedicles of neighboring vertebrae at all levels in the spine.
What is Flavum?
The ligamenta flavum is a short but thick ligament that connects the laminae of adjacent vertebrae from C2 to S1 and is considered a medial ward continuation of the fact joint. It consists of 80% elastin fibers and 20% collagen fibers.
Which of the following might be lost when the mammillary bodies are damaged?
Damage to the mammillary bodies due to thiamine deficiency is implied in pathogenesis of Wernicke–Korsakoff syndrome. Symptoms include impaired memory, also called anterograde amnesia, suggesting that the mammillary bodies may be important for memory.
What is Supraspinous ligament?
The supraspinous ligament or supraspinal ligament is a strong fibrous cord that connects together the apices of the spinous processes from the seventh cervical vertebra to 3rd or 4th lumbar vertebrae.
What is the purpose of the articular processes of the vertebrae?
The functional significance of the articular processes is obviously to limit rotation, which can take place in the lumbar segment of the vertebral column during any asymmetrical movement of the body.
Is your neck connected to your spine?
The neck is connected to the upper back through a series of seven vertebral segments. The cervical spine has 7 stacked bones called vertebrae, labeled C1 through C7. The top of the cervical spine connects to the skull, and the bottom connects to the upper back at about shoulder level.
What joint is between articular processes?
The facet joints, (or zygapophysial joints, zygapophyseal, apophyseal, or Z-joints) are a set of synovial, plane joints between the articular processes of two adjacent vertebrae. There are two facet joints in each spinal motion segment and each facet joint is innervated by the recurrent meningeal nerves.
