Skeletal System
Pathological Conditions
-
-
Osteoporosis
Bone density decreases, increasing fracture risk.
-
Fractures
Broken bones which can be of various types like simple, compound, spiral, etc.
Skeleton
Function
The skeleton provides a rigid framework that supports and protects the body, facilitates movement, produces blood cells, and stores minerals.
Types of Bones
Short Bones
Almost cube-shaped (e.g., bones of the wrist and ankle).
Flat Bones
These bones are thin and broad (e.g., skull and scapula).
Long Bones
These are longer than they are wide (e.g., femur and humerus).
Irregular Bones
These have complex shapes (e.g., vertebrae and some facial bones).
-
Bone Matrix
Made up of collagen fibers and inorganic minerals, providing tensile strength and rigidity, respectively.
Joints
Function
Joints allow bones to move relative to one another. They provide mechanical support and allow for flexibility
Types of Joints
Fibrous Joints
Immovable or slightly movable (e.g., sutures in the skull)
Cartilaginous Joints
Allow limited movement and are connected by cartilage (e.g., intervertebral discs).
Synovial Joints
Highly movable and characterized by a cavity filled with synovial fluid (e.g., knee, elbow).
Synovial Fluid
Lubricating fluid found in synovial joints, reducing friction and nourishing cartilage.
Ligaments
Fibrous connective tissues that connect bones to other bones, adding stability to the joints.
Muscles
Function
Muscles produce movement by contracting and relaxing in response to neural stimulation. They also maintain posture and produce heat.
-
Tendons
Connect muscles to bones, transmitting the force produced by muscle contraction to move the bones.
