SKELETAL SYSTEM Jeremy G. Vicencio Department of Biology University University of the Philippines Manila 1st Semester, A.Y. 2011-2012
The Skeleton •
•
•
Support for the animal body Terrestrial environment – prevents the animal’s body from collapsing under its own weight. Aquatic environment – supports the shape of the animal’s body to counteract the pressure that acts on it.
Types of Skeleton
Chemical Composition of Various Exoskeletons Organism
Type
Composition
Radiolarians
Shell with testa
Strontium sulfate or silica
Arthropods
Chitinized cuticle/carapace
Mineralized chitin
Mollusks
Shell
Chonchiolin with Calcium carbonate
Echinoderms
Ossicles
Calcium carbonate
Turtles
Carapace and plastron/scutes
Calcium carbonate or keratin
Chemical Composition of Various Exoskeletons Organism
Type
Composition
Sponges
Spicules, spongin
Silica, calcium carbonate
Corals
Spicules
Calcium carbonate
Vertebrates
Bone
Calcium or Magnesium phosphate, collagen, glycosaminoglycans
Bone Formation Bone always arises by the replacement of some
pre-existing tissue •
•
If the pre-existing tissue is hyaline cartilage, the process is called endochondral ossification (long bones) If the pre-existing material is embryonic mesenchyme, the process is called intramembranous ossification (flat bones of the skull)

OIA •
Origin –
•
Insertion –
•
Relatively fixed point of attachment Relatively movable point of attachment
Action –
Accomplished by contraction or shortening in length
Actions of Skeletal Muscles Muscle Function
Extensor Straightens a joint Flexor Bends a joint Abductor Moves a body part away from the midline of the body Adductor Moves a body part toward the midline of the body Levator Raises a body part Depressor Lowers a body part Protractor Causes a body part to be thrust forward or outward Rotator Rotates a body part
