Study Notes
Axial Skeleton
- Includes the skull, vertebral column, and rib cage.
- Supports the head and trunk, protecting the brain, spinal cord, and thoracic organs.
Elbow Joint
- Classified as a hinge joint.
- Allows movement primarily in one plane, flexion, and extension.
Parts of a Typical Long Bone
- Diaphysis: Shaft or long part of the bone.
- Epiphysis: End parts of the bone that connect with adjacent bones.
- Metaphysis: Region between diaphysis and epiphysis, where growth occurs in children.
Bone Tissue
- Compact bone is the hardest connective tissue in the body.
- Provides strength and support, forms the outer layer of bones.
Function of the Axial Skeleton
- Serves to support and stabilize the body structure.
- Protects vital organs including the brain, heart, and lungs.
Muscle Forms by Shape
- Muscles can be categorized into various shapes including spherical, flat, and long.
- Example includes fusiform muscles which are spindle-shaped.
Fleshy Part of a Muscle
- Known as the belly or body of the muscle.
- Contains the muscle fibers responsible for contraction.
Muscle Attachment Types
- Broad, flat tendon attachment is referred to as an aponeurosis.
- Connects muscle to a broad area on another structure.
Movement Terms
- Flexion refers to decreasing the angle between body parts, commonly seen in hinge joints.
- Important in movements such as bending the elbow or knee.
Seam in Muscle Attachment
- The term for a line or seam where two structures meet is called a suture.
- Especially relevant in the context of bones in a fused structure.
