# Friday 29th November 2024 ## The Muscles - Pectoral, Rotator Cuffs, Pectorial, Trepersus. - Tricep-Benep, Lutssiumus Dorssi - Hip Recrons, Glutaubs, Maxius. - Hamstrings, Quadricep, Frustrones, Fubiecer lastenice. - Tubius Anterior, Gastroneus **1. Tendons** attaches muscle to bone. **2. Ligaments** attaches bone to bone. **3. Sprain** is when you damage a joint. **4. Rest, Ice, Compress** You don't really know ## Muscles make up 40% of your total body weight. It takes less time to gain muscle than it does to lose it. The smallest muscles are found in the ear, you use 200 muscles. To take one step, you use 200 muscles. ## Humans are rich with all the muscles fibres that will ever have. Your tongue is the strongest muscle in your body. ## An example of the muscular and skeletal systems working together could be biceps and triceps. **Muscles are arranged in antagonistic pairs.** As one muscle contracts (shortens) it's partner relaxes (lengthens). **The muscle which contracts is called the agonist or prime mover.** The muscle which relaxes is called **the antagonist**. **They swap actions to reverse the movement.** ## Antagonistic pairs - The Bicep, Tricep | Action | Joint Movement | Agonist | Antagonist | |---|---|---|---| | Upword Phase | Hinge joint | Biceps | Triceps | | by the being | Flexation | | | | urd | | | | | Downward | Hinge joint | Triceps | Biceps | | Phase & | Extention | | | | Bicepure | | | | | Action | Joint Movement | Agonist | Antagonist | |---|---|---|---| | Straightening | Extention | Quads | Hamstring | | & | | | | | Holly | | | | | Bending & | Flextion | Hamstring | Quads | | Holly | | | | **Isotonic = Muscle action where the muscle changes length when it contracts, resulting in limb movement, eg. straightening arm.** **Isotonic Concentric = Isotonic contraction where the muscle shortens, eg. bicep curl.** **Isotonic Eccentric = Isotonic contraction where the muscle lengthens, eg. downward phase bicep curl.** **Isometric = Muscle action when the muscle stays the same length so no movement, eg. holding weight. ** # Friday 6th December 2024 ## Types of Movement **Flexing - Flexion is when the angle between bones become shorter.** **Extension - When there is an increase in a angle of the joint.** **Abduction is movement away from the midline of the body, or lateral movement to the side.** **Adduction is movement back towards the body middle line. This can be known as medial movement.** **Circumduction is the movement of the body in a circular manner.** ## Rotation **Rotation is only allowed motion at a pivot joint.** - **Lateral -** quid & socket - **Pivots** - or ball & socket - **Medial** - **Neck** - **Lower limbs** **Suplanation and Promasticon (Hands)** **Upper limbs facing Forwad is Supination** **Promation palms facing down (Toes)** **Dorsiflexion and Plantar Flexor (Toes/heal)** **Dorsiflexion is toes pointing upwards** **Plantar Flexion is toes pointing to the floor.** **Inversion and Eversion (Foot in and out)** - Not at ankle - **Eversion** Foot goes outward. - **Inversion** Foot goes inward - **Inversion** has a greater range. ## Muscle Fatigue **It's when were initially generating a normal amount of force, we experience a declining ability to generate force. This happens after vigorous exercise. ** **Muscle soreness is after muscle fatigue cause of micro tears.** **Muscle Fatigue is mainly caused to the build up of lactic acid that accumulate in the muscles.** This has been regarded as the most important cause of skeletal muscle fatigue. **Lactic Acid makes the burning feeling.** ## Discontinuous Data. **Discontinuous data has a limited amount of data with only groups and you cannot have anything in between. eg. Blood Type. ** A bar chart is shown with labels on the x-axis for blood types A, B, AB, and O. The y-axis is labeled from 0 to 35. The bar for A is around 35, the bar for B is about 10, the bar for AB is about 5, and the bar for O is around 35. The bars reach different points on the y-axis.
