Study Notes
Friday 29th November 2024 - The Ghusles
- Muscles and Bones: Tendons attach muscles to bones, ligaments attach bone to bone. Sprains occur when a joint is damaged.
- Rest, Ice, Compression: Muscle recovery involves rest, ice, and compression. Building muscle takes longer than losing it. Smallest muscles (e.g., in hand) are ~200.
- Muscle Pairs: Muscles work in pairs (antagonistic pairs). One muscle contracts (agonist), while the other relaxes (antagonist). This reverses the movement.
Types of Movements
- Flexion: Decreasing the angle between two bones.
- Extension: Increasing the angle between two bones.
- Abduction: Moving a limb away from the midline of the body.
- Adduction: Moving a limb towards the midline of the body.
- Rotation: Circular movement around an axis.
Muscle Types and Actions
-
Isotonic: Muscle changes length.
-
Isometric: Muscle stays the same length.
-
Supination/Pronation: Turning the forearm so palm is up(supination) or down(pronation).
-
Dorsiflexion: Movement of the foot upwards.
-
Plantar flexion: Movement of the foot downwards.
-
Inversion: Turning the foot inwards
-
Eversion: Turning the foot outwards
Muscle Fatigue
- Muscle fatigue occurs due to lactic acid buildup.
- Rest and recovery are necessary for muscle repair.
Discontinuous Data
- Limited data groups make generalization difficult; e.g., blood type.
Graph of Blood Types
- A graph shows the percentage occurrence of different blood types (A, B, AB, O).
