What kind of tissue makes up the intervertebral disc?
What kind of tissue makes up the intervertebral disc?
Fibrocartilage
Answer to: What kind of tissue makes up intervertebral discs? Fibrocartilage.
What type of tissue are intervertebral discs composed of quizlet?
The type of cartilage found in the intervertebral discs is fibrocartilage. The pubic symphysis and the menisci in the knee joints also have fibrocartilage. The external ear has elastic cartilage. Hyaline cartilage is found in the fetal skeleton, articular cartilage, costal cartilage, larynx, trachea, and nose.
Where are intervertebral discs located?
vertebrae
The intervertebral discs (or discs) are fibrocartilages lying between adjacent surfaces of the vertebrae. They form a fibrocartilaginous joint between the vertebral bodies, linking them together.
What is the most rigid type of connective tissue?
Bone is the hardest connective tissue. It provides protection to internal organs and supports the body. Bone’s rigid extracellular matrix contains mostly collagen fibers embedded in a mineralized ground substance containing hydroxyapatite, a form of calcium phosphate.
What is the strongest cartilage?
Fibrocartilage contains even more collagen fibers than hyaline cartilage. It’s the most rigid type of cartilage and can be found in intervertebral discs in the spine. It’s also the strongest type of cartilage.
Which tissue has the poorest blood supply?
Anatomy – Connective Tissue
| A | B |
|---|---|
| dense and cartilage connective tissue | type of connective tissue that has poor blood supply and therefore heals slowly |
| cartilage | connective tissue which provides support, frameworks, and attachments |
| cartilage | connective tissue which provides structural models for many developing bones |
What makes up the center of the intervertebral disc?
Between the vertebrae, the notochord expands to form the gelatinous centre of the intervertebral disc – the nucleus pulposus. This nucleus is later surrounded by circularly arranged fibres that form the anulus fibrosus. The anulus fibrosus and nucleus pulposus together constitute the intervertebral disc.
Are there any blood vessels in the intervertebral discs?
The intervertebral discs, like other cartilages, have no blood supply. They form the largest structures in the body without their own blood vessels. During embryonic development, and at birth, they possess some vascular supply which terminate in their endplates and anulus fibrosus.
Where does the notochord go in an intervertebral disc?
As development progresses, the notochord degenerates and disappears where it is surrounded by the developing vertebral bodies. Between the vertebrae, the notochord expands to form the gelatinous centre of the intervertebral disc – the nucleus pulposus. This nucleus is later surrounded by circularly arranged fibres that form the anulus fibrosus.
What kind of pain does an intervertebral disc cause?
Most of those sinovertebral nerves are meningeal branches of spinal nerves. Intervertebral disc anomalies can lead to symptoms of back pain, neck pain, and sciatica. There are many other causes of back pain and sciatica, for example spinal stenosis, osteoarthritis in the spine, and spondylolisthesis.
What type of cartilage is in the intervertebral disks?
Two main parts of the intervertebral discs are the outer ring (annulus fibrosus) and the inner gelatinous material. (nucleus pulposus). The outer ring consists of fibrocartilage (type I collagen) , while the inner material shows many similarity to the articular hyaline cartilage both in its biochemical (type II collagen) and histological appearance.
What are the two parts to the intervertebral disk?
The intervertebral discs are the largest structures in the body without a vascular supply. By means of osmosis, each disc absorbs needed nutrients. Each disc is made up of two parts: the annulus fibrosus and the nucleus pulposus . The annulus is a sturdy tire-like structure that encases a gel-like center, the nucleus pulposus.
What is loss of intervertebral disk space?
Loss of intervertebral disc space can be due to a variety of causes: degenerative disc disease of the spine: most common cause. trauma .
What is a rupture of the intervertebral disk cartilage?
MECHANISM Rupture of the intervertébral disc occurs with the spine in a position of flexion . Of course, the predisposing factors must exist and the precipitating factor, trauma, must come into being. Flexion narrows the intervertébral space anteriorly and widens the space posteriorly.
