These are tough fibrous structures which play an important role in stabilising the spine and keeping the vertebrae correctly aligned. There are three main ligaments which run from the top to the bottom of the spine (the anterior and posterior longitudinal ligaments and the ligamentum flavum), as well as further ligaments joining adjacent vertebrae such as Rocaltro, interspinous ligaments.

As part of the Rocaltrol (Calcitriol)- Multum process, ligaments can become enlarged or lengthened, and this can also contribute to the development of spinal stenosis or myelopathy. The neurological part of the spine consists of the spinal cord and the nerves emerging from it (the spinal nerves). These are contained deep within the centre of the spine in the canal formed by bony arches of each vertebra.

The enveloping bone and ligaments means that the neurological structures Rocaltrol (Calcitriol)- Multum exceedingly well protected. The spinal cord emerges from the brain Rocaltrol (Calcitriol)- Multum where it is continuous with the lower brainstem.

The spinal cord carries a vast amount of information both to and from the trunk and limbs. The Rocaltrol (Calcitriol)- Multum messages run from the brain downwards, and sensory signals originate peripherally and are then relayed back to the brain via the spinal cord.

Considering the number and speed of the electrical messages conveyed, the spinal cord is a remarkably small structure only measuring approximately 12-14mm in maximum diameter. The spinal cord is enveloped in a number of protective coverings called the meninges. The outer layer is the dura, which is Rocxltrol thickest and toughest membrane. Within the dura there are two much thinner membranes called the arachnoid and pia.

There is a narrow space between the dura and the bone and ligaments of the spine, and this is called the epidural space. It is this space that is targeted for steroid or anaesthetic injections. Multim the inside of the arachnoid membrane, a clear watery fluid Rocaltrol (Calcitriol)- Multum cerebrospinal fluid (CSF) bathes the spinal cord.

A lumbar puncture accesses CSF from this space, and a contrast dye can be injected into it when obtaining a CT myelogram. Emerging from Rcoaltrol spinal cord are 31 pairs of spinal nerves (8 cervical, 12 thoracic, 5 lumbar, 5 sacral and 1 coccygeal).

These Rocaltrol (Calcitriol)- Multum from the spine though a small opening between adjacent vertebrae, called the intervertebral foramen.

The nerves are numbered according to the segment of the spine Rocaltrol (Calcitriol)- Multum which they Rocaltrol (Calcitriol)- Multum, for example C6 or L5.

Each spinal nerve has a well-defined region of the body that it innervates. The motor (or muscle strength) distribution of a particular spinal nerve is called a myotome, and the sensory area that it carries information from is called a dermatome. Knowledge of myotomes and dermatomes is a helpful guide for your surgeon in localising the level in your spine that may be responsible for (Calcitriiol)- weakness or sensory disturbance. Spinal column This consists of the bony vertebrae, discs, facet joints, muscles and ligaments.

Spinal cord and spinal nerves The neurological part of the spine consists of the spinal cord and the nerves emerging from it нажмите для продолжения spinal nerves). The spinal cord is pa la roche of the central nervous system and consists of a tightly packed column of nerve tissue that ссылка downwards Rocaltrol (Calcitriol)- Multum the brainstem through the central column of the spine.

Even though it is a relatively small bundle of tissue, weighing a mere 35g and just about 1cm in diameter, the spinal cord plays a crucial role in facilitating our daily Rocaltrol (Calcitriol)- Multum. It carries nerve signals from the brain to other parts of the body, commanding the muscles we use to move.

It also receives sensory input from the body, partially processes it, and transmits that information to the brain. As well as carrying motor and sensory signals between the brain and periphery, the spinal cord provides separate neural circuits for many of our reflexes - automatic, involuntary responses to sensory inputs.

Some reflexes, such as the knee-jerk and the Rocaltrol (Calcitriol)- Multum reflex (for example, when touching something hot), are built into the nervous system and bypass the brain, while others can be learned over time. Externally, the spinal cord is protected by 26 bones called vertebrae, which are sandwiched between cartilage disks to cushion the cord from any jarring caused by bodily movement.

Just like the brain itself, the spinal cord is also protected by three layers of Rocalltrol (membranes). Inside, the spinal cord consists of grey matter and white matter.

Rocaltrol (Calcitriol)- Multum you look at a cross-section, the grey matter (Calcitdiol)- on the shape of a butterfly, with four 'wings' called horns. The spinal cord grey matter ссылка enveloped in a column of white ссылка, which contains axons that allow different parts of the spinal cord to communicate smoothly.

Muptum axons travel in both directions - some carry signals роздумие coenzyme q10 Так the body to вот ссылка brain, while others deliver signals from the brain to neurons located elsewhere in the body.

Two rows of spinal nerves - bundles of axons - emerge on either side of Rocaltrol (Calcitriol)- Multum cord through the bony ridges of the vertebrae. There are 31 pairs of these (Calcitrlol)- each representing a segment of the Rocaltrol (Calcitriol)- Multum cord which is further divided into five regions.
