Skeletal System Flashcards
skeletal systems made of chitin and calcium carbonate that provides protection to creatures such as insects and crustacea
Exoskeleton
Internal skeleton of an animal (vertebrate), which is comprised of bone and cartilage
Endoskeleton
Support and Protect
Homeostasis
Produce Blood Cells
Storage
Movement
What are the 5 functions of the skeletal system
This function of the skeletal system supports soft tissue, provide points of attachment for skeletal muscles, and provides protection for internal body organs
Support and Protect
The skeletal system works with which other system to allow for movement
muscular system
Red bone marrow inside some larger bones produce this
blood cells
The interior of the bone can store these things
minerals and chemical energy
Bones are able to absorb or release calcium into the blood to maintain a stable environment
homeostasis
How many bones are in the human skeleton
206
the appendages, arms and legs and the shoulder girdle, and pelvic girdle.
appendicular skeleton
how many bones are in the appendicular skeleton
126
the bones of the body which protect the internal organs
axial skeleton
how many bones are in the axial skeleton
80
This type of bone makes up the dense outer layer
compact bone
this part of the bone is found inside bones and is light, less dense, and porous
spongy bone
soft connective tissue that produces blood cells, found in the pores of spongy bone
bone marrow
tough, fibrous, membrane that covers and protects the outer surface of the bone
periosteum
holds the skeleton together and supports movement
joints
connective tissue that attaches muscles to bones
tendons
connective tissue that attaches bones to bones
ligaments
loss of bone tissue particularly in elderly people
osteoporosis
softening of bones associated with vitamin D deficiency
osteomalacia
inflammatory disease that damages joints and surrounding tissue
arthritis
side to side curve in the spine
scoliosis
cancer found in bones
bone cancer
injury to bones, takes about 100 lbs of pressure
breaks, strains, and fractures
