5.1 Skeletal Tissue Flashcards
Bone is a type of _____ tissue
Connective
All connective tissues are derived from
Mesenchyme (embryonic stem cell)
Chondroblast
Cartilage stem cell
Osteoblasts
Bone tissue
Fibroblasts
Collagen, elastic fibers, connective tissue proper
Blood stem cells
Give rise to all of the stem cells; formed elements of your blood
Mesenchyme (connective tissues) four categories
- chondroblast
- osteoblast
- fibroblast
- blood stem cells
Chondroblasts differentiate into
Chondrocytes (cells of cartilage)
Fibrocytes give rise to
Connective tissue proper
Blood stem cells become formed elements of blood:
Water, matrix, cellular debris, proteins
Most of your bones are first patterned out of _____.
Cartilage
Properties of cartilage:
- mostly water
- highly resilient tissue (pliable)
- abundant in embryo
Three types of cartilage:
- hyaline (most abundant and basic, aka glass cartilage) nose and trachea
- elastic (+elastic fiber, recoil) ear & epiglottis
- fibrocartilage (+collagen) padding between joints and spine
Bones are ____ that contain several types of ______.
Organs, tissues
Bone tissue is primarily _______ material
Inorganic (~65%) Crystalline salts (calcium phosphate)
