What are the 2 components of an intervertebral disc quizlet?
Each disc is made up of two parts: the annulus fibrosus (which means, roughly, the fibrous ring) and the nucleus pulposus (which means the pulpy interior).
What are the component parts of the intervertebral disc?
The intervertebral disc is made up of two components: the annulus fibrosus and thenucleus pulposus. The annulus fibrosus is the outer portion of the disc. It is composed of layers of collagen and proteins, called lamellae.
What are the components of intervertebral discs quizlet?
The intervertebral disc consists of two components. The — is the fibrocartilagenous outer region of the intervertebral disc, which surrounds the jelly-like middle region called the nucleus pulposus. The — is the inner gelatinous (jelly-like) region of the disc.
What are the 2 main functions of an intervertebral discs?
The intervertebral discs have the following functions: They provide cushioning for the vertebrae and reduce the stress caused by impact. By keeping the vertebrae separated from each other, they act as a type of shock absorber for the spine. They help protect the nerves that run down the spine and between the vertebrae.
What are intervertebral discs quizlet?
Intervertebral discs separate the vertebrae of the spinal column and help absorb shock for the spine. An intervertebral disc disease involves the deterioration, herniation, or other dysfunction of the intervertebral discs. Disc disorders can affect the cervical, thoracic, and lumbar spine.
Where is the intervertebral disc located quizlet?
Intervertebral discs can be found between the bodies of vertebrae from C2 to the sacrum. As you recall, they are made of fibrocartilage to give strength, permit movement, and absorb shock.
What are discs made?
The intervertebral discs are complex structures that consist of a thick outer ring of fibrous cartilage termed the annulus fibrosus, which surrounds a more gelatinous core known as the nucleus pulposus; the nucleus pulposus is sandwiched inferiorly and superiorly by cartilage end-plates.
Is intervertebral discs made of fibrocartilage?
The intervertebral disc (IVD) is important in the normal functioning of the spine. It is a cushion of fibrocartilage and the principal joint between two vertebrae in the spinal column.
Where are the intervertebral discs found?
An intervertebral disc (or intervertebral fibrocartilage) lies between adjacent vertebrae in the vertebral column. Each disc forms a fibrocartilaginous joint (a symphysis), to allow slight movement of the vertebrae, to act as a ligament to hold the vertebrae together, and to function as a shock absorber for the spine.
What is intervertebral disk?
The intervertebral discs provide cushioning between vertebrae and absorb pressure put on the spine. While the discs in the lower (lumbar ) region of the spine are most often affected in intervertebral disc disease, any part of the spine can have disc degeneration.
What are intervertebral discs made of hyaline cartilage?
The intervertebral disk end plate comprises a thin layer of hyaline cartilage that is bonded to an underlying layer of perforated cortical bone. On the disk side, the hyaline cartilage blends in with the nucleus and annulus.
How is the intervertebral disc formed?
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.
What type of connective tissue are the intervertebral discs made of?
Fibrocartilage is a mixture of dense regular connective tissue and hyaline cartilage. It is found in intervertebral discs, pubic symphysis, articular discs and menisci of joints.
What specific type of tissue makes up the intervertebral discs quizlet?
The type of cartilage found in the intervertebral discs is fibrocartilage.
What 2 spinal curvatures are obvious at birth?
which two spinal curvatures are obvious at birth? under normal development. these are the cervical curvature, which develops first with infant heat lifting and the lumbar curvature, which develops next sitting up. these curvatures prepare the spine for ambulation.
What is the tough tissue found in the intervertebral discs and pubic symphysis quizlet?
Fibrocartilage is a type of cartilage that contains fine collagen fibers arranged in layered arrays. Located at pads within knee joint, between pubic bones of pelvis, and intervertebral discs. Functions to resist compression, prevent bone-to-bone contact, and limits movement. Dense bone that contains parallel osteons.
What tissue are tendons and ligaments made of?
loose connective tissue
Tendons and ligaments are mainly composed of type I collagen fibers surrounded by a mesh of loose connective tissue. The whole tendon transmits forces from muscle to bone. However, it also shows viscoelastic behavior such as creep or stress relaxation.
What is the composition of ligaments?
A ligament is composed of dense fibrous bundles of collagenous fibres and spindle-shaped cells known as fibrocytes, with little ground substance (a gel-like component of the various connective tissues).
What type of tissue is a ligament composed of?
Ligaments are made out of connective tissue that has a lot of strong collagen fibers in it. They are found in different shapes and sizes in the body.
