Which statements characterize the functions of cartilage?

What is in the central canal of bone?
Running down the center of each osteon is the central canal, or Haversian canal, which contains blood vessels, nerves, and lymphatic vessels. These vessels and nerves branch off at right angles through a perforating canal, also known as Volkmann's canals, to extend to the periosteum and endosteum.
What is the central canal of compact bone quizlet?
Compact bone is laid down around the central canal in rings (lamellae). The hollow center of an osteon, also known as a Haversian canal. The central canal contains blood vessels, lymphatic vessels, lymphatic vessels, and nerves.
What is true about osteons?
Osteons are formations characteristic of mature bone and take shape during the process of bone remodeling, or renewal. New bone may also take this structure as it forms, in which case the structure is called a primary osteon.
What is found in a central Haversian canal?
The hollow center of an osteon, also known as a Haversian canal. The central canal contains blood vessels, lymphatic vessels, lymphatic vessels, and nerves. Bone is laid down around the central canal in concentric rings called lamellae.
What is found in the central canal?
Function. The central canal carries cerebrospinal fluid (CSF), which it receives from the ventricular system of the brain. The central canal helps to transport nutrients to the spinal cord as well as protect it by cushioning the impact of a force when the spine is affected.
What structures are located in the central canal?
The central canal is part of a system of cerebrospinal fluid (CSF) cavities that includes the cerebral ventricle, aqueduct of Sylvius, and fourth ventricle (Figures 3-4) (2). It is situated in the gray commissure, which (along with the anterior white commissure) connects the two parts of the spinal cord.
What are osteons?
osteon, the chief structural unit of compact (cortical) bone, consisting of concentric bone layers called lamellae, which surround a long hollow passageway, the Haversian canal (named for Clopton Havers, a 17th-century English physician).
What is the name of the canal that connects osteons to other osteons?
Osteons are connected to each other and the periosteum by oblique channels called Volkmann's canals or perforating canals.
Which statements are functions of cartilage quizlet?
Which statements characterize the functions of cartilage? – It provides a model for the formation of bones. – It covers the ends of long bones. Choose the bones produced through intramembranous ossification.
What are the functions of cartilage?
Cartilage has many functions, including the ability to resist compressive forces, enhance bone resilience, and provide support on bony areas where there is a need for flexibility. The primary cell that makes cartilage is the chondrocyte, which resides within the lacunae.
What is found within the central canal quizlet?
The central canal contains blood vessels, lymphatic vessels, lymphatic vessels, and nerves.
What are osteons composed of?
The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.
What is the central canal of a bone?
The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.
What is central canal quizlet?
central canal (haversian canal) vertical canals, the hollow center of an osteon, also known as a Haversian canal. The central canal contains blood vessels, lymphatic vessels, lymphatic vessels, and nerves. Bone is laid down around the central canal in concentric rings called lamellae.
What is an osteon quizlet?
Osteon. The basic unit of structure in adult compact bone, consisting of a central (haversian) canal with it's concertrically arranged lamellae, lacunae, osteocytes, and canaliculi.
What is the function of an osteon?
Osteons (the Haversian system) form structural and functional units of cortical bone. In recent years, emerging evidences have shown that the osteon structure (including osteocytes, lamellae, lacunocanalicular network, and Haversian canals) plays critical roles in bone mechanics and turnover.
Where are central canals found?
The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.
What is the central canal of the spinal cord quizlet?
The central canal contains blood vessels, lymphatic vessels, lymphatic vessels, and nerves. Bone is laid down around the central canal in concentric rings called lamellae. Posterior side white matter tract on the dorsal side of the spinal cord, carrying touch and proprioceptive axons to the brain stem.
How do I identify my central canal?
The central canal, also referred to as the spinal foramen or ependymal canal, extends from the conus medullaris in the lumbar spine to the caudal angle of the fourth ventricle and is lined by a single layer of columnar ependymal cells (2). It represents the remnant of the lumen of the primitive neural tube.
What are osteons made up of?
The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.
