System
- Which are the organs that
are part of the
musculoskeletal system?
The main organs and tissues that are
part of the musculoskeletal systemhumans are the cartilages, the bones in
and the muscles.
- What are the functions of
the musculoskeletal system?
The musculoskeletal system has the
functions oorgans, maif supporting antenance of the body spatialnd protecting (^)
conformation, motion of organs, limbs
and bodily portions and nutrient storag(glycogen in muscles, calcium and e
phosphorus in bones).
- Which type of tissue are the
cartilaginous and the osseous
tissue?
The cartilaginous and the osseous
tissues are tissues since thconsidered connectiveey are tissues in which (^)
the cells are relatively distant from
others with a extracellular matrix in the interstitialgreat amount of (^)
space.
- What are the cells that form
the cartilaginous tissue?
The main cells of the cartilages are the
chondrocytes,chondroblasts that secrete th originated from the e
intersticial matrix. There are also
chondroclasts,lisosomes and responsible f cells with manyor the (^)
digestion and remodelation of the
cartilaginous matrix.
- What is the constitution of
the cartilaginous matrix?
The cartilaginous matrixcollagen fibers, mainly collage is made ofn type II, (^)
and of proteoglycans, proteins
associated to gchiefly hyaluronic acid. Tlycosaminoglycans,he
proteoglycans provide the typical
rigidity of the cartilages.
- What are some functions of
the cartilages in the human
body?
Cartilagstructural sues are responsible pport of the nose and ears.for the (^)
The trachea and the bronchi are also
organs with prevent the closing cartilaginous structures thatof these tubes. In
joints there are cartilages that cover the
bones providing a smootreduce the friction of the jointh surface to
movement. In the formation of bones
the cartilages actare gradually substituted b as a mold and theyy the osseous (^)
tissue.
