The human skeletal system is made up of
|
bones, joints, cartilage and ligaments
|
|
|
The major function of the skeletal system is
|
to provide protection to organs
|
|
|
Bone marrow, which is found in the middle of many bones produces
|
red blood cells
|
|
|
Bone interacts with the ___________ system
|
Endocrine
|
|
|
What are the two major hormones that act on bone and play a role in bone formation and remodeling.
|
Calcitonin and Parathyroid
|
|
|
Bones release their own hormone called? What does it do?
|
Osteocalcin
Plays a role in blood sugar regulation and bone formation |
|
|
How many bones are in the adult body?
|
206
|
|
|
The human skeleton is divided into two major categories
|
Axial Skeleton
Appendicular Skeleton |
|
|
The axial skeleton is made up of bones found along the ________________ axis of the body.
|
Central vertical. Its the "core" of the body. Pelvis, arms and legs attach. It supports head, chest and spinal column and makes human upright posture possible.
|
|
|
The appendicular skeleton contains which bones?
|
The "appendages" (good way to remember) It contains the arms and legs, and pelvis. It is part of the body that makes walking possible.
|
|
|
What is the area known as where tow bones articulate or come in contact with one another?
|
Joint
|
|
|
What are the six major joints in the body?
|
Ball and Socket
Condyloid Gliding Joints Hinge Joints Pivot Joints Saddle Joints |
|
|
A wide range of motion joint that includes rotation. Examples are the hip and shoulder joints.
|
Ball and Socket
|
|
|
This joint allows movement along two plains, but no rotation. Examples include, jaw and fingers.
|
Condyloid
|
|
|
This joint allows bone surface to glide past eachother, movement directions are limited. Examples include wrists and ankles.
|
Gliding Joints
|
|
|
This joint allows motion along one plane only. Examples include the elbow.
|
Hinge Joints
|
|
|
This joint allows rotation around other bones. Examples include neck bones and radius of the forearm.
|
Pivot Joints
|
|
|
This joint allows back and forth, side to side motions but no rotation. A major example of this is the thumb.
|
Saddle Joint
|
|
|
This cushions our joints and sometimes hold them together. It acts as a shock absorber and reduces friction between two bones.
|
Cartilage
|
|
|
What type of cartilage makes up the rib cage?
|
Costal Cartliage
|
|
|
What type of cartilage makes up the nose?
|
Alar Cartliage
|
|
|
What type of cartilage makes up the spinal column?
|
Intervertebral Disks
|
|
|
What type of cartilage makes up the bronchial tubes?
|
Hylaline Cartliage
|
|
|
Tough, fibrous tissues that connect bones to bones.
|
Ligaments
|
