Bones And Joints Flashcards
What are the 7 classifications of bones?
Sutures Bones
Pneumatized bones
Flat Bones
Irregular Bones
Short Bones
Long Bones
Sesamoid Bones
Where do the Axial and Appendicular Skeleton attach to each other?
The Pectoral girdle and pelvic Girdle
What does a “Process” mean in bone markings?
Any projection or bump on the bone
What is a “Ramus” on the bone?
An extension of a bone making an angle to the rest of the structure
What is a Sinus or Antrum in a bone?
Sinus or antrum’s are chambers within a bone which are normally filled with air
What is a Meatus or Canal in a bone?
A passageway through the substance of a bone
What is a Fissure in a bone?
An elongated cleft
(A cleft is a gap or split on the structure of a body)
What is a “Foramen” in a bone?
A rounded passageway for blood vessels and/or nerves
What do joints do and how are they held together?
Joints help permit movement and are connections between the bones, they are usually held together through cartilage, fluid or dense connective tissue
What is Synarthroses?
Synarthroses are Immovable joints
What are the three types of Synarthrosis joints
Fibrous, Cartilaginous and “Bony Fusion”
What is a “Fibrous” Joint?
Fibrous joints are joints that have dense fibrous tissue that bind the bones and anatomical structure together
(Ex: Sutures in the skull and Gomphosis in the teeth)
Give an example of a cartilaginous and bony fusion joint.
Synchondrosis, is a joint in which hyaline cartilage is used to connect the structures together (cartilaginous)
Synostosis is an example of bony fusion as it is when two bones fuse together to form a single bone
(Bony Fusion)
Define Amphiarthrotic joints
Joints that are “In-Between”, and allow slight movement in the joint
What is Syndesmosis?
Syndesmosis is when bones are connected by long connective tissue ligaments
(Syndesmosis is also an example of an amphoarthrotic joint)
