MUSCLE TISSUE & NEUROMUSCULAR FUNCTION
1.2.2 Distinguish between the different types of muscle
- Include smooth, cardiac and skeletal
1.2.1 Outline the general characteristics common to muscle tissue
- Limit to contractility extensibility, elasticity, atrophy, hypertrophy, controlled by nerve stimuli and fed by capillaries
1.2.3 Annotate the structure of skeletal muscle
- Limit to epimysium, perimysium, endomysium, muscle fiber, myofibril, sarcomere, actin and myosin
4.1.4 Label a diagram of a motor unit
- Limit to dendrites, cell body, nucleus, axon, motor end plate, synapse and muscle
4.1.2 Explain the role of neurotransmitters in stimulating skeletal muscle contraction
4.1.3 Explain how skeletal muscle contracts by the sliding filament theory
4.1.4 Explain how slow and fast twitch fiber types differ in structure and function
MUSCULAR SYSTEM
1.2.4 Define the terms ORIGIN and INSERTION of muscles
- Origin: The attachment of a muscle tendon to a stationary bone.
- Insertion: The attachment of a muscle tendon to a movable bone
1.2.5 Identify the location of skeletal muscles in various regions of the body
- Anterior muscles: Deltoid, pectoralis, iliopsoas, sartorius, quadriceps femoris (rectus femoris, vastus lateralis, vastus medialis, vastus intermedius), tibialis anterior, abdominus rectus, external obliques, biceps brachii.
- Posterior muscles: Trapezius, triceps brachii, latissimus dorsi, gluteus maximus, hamstrings (biceps femoris, semitendinosus, semimembranosus,) gastrocnemius, soleus, erector spinae.
MUSCLE MOVEMENT
4.2.2 Outline the types of muscle contraction.
- Consider isotonic, isometric, isokinetic, concentric and eccentric.
4.2.3 Explain the concept of reciprocal inhibition.
- Consider agonist and antagonist.
4.2.4 Analyze movements in relation to joint action and muscle contraction.
- For example, during the upward motion of a bicep curl the joint action is flexion. The bicep contracts concentrically while the tricep relaxes eccentrically.
4.2.5 Explain delayed onset muscle soreness (DOMS) in relation to eccentric and concentric muscle contractions.
- DOMS results primarily from eccentric muscle action and is associated with structural muscle damage, inflammatory reactions in the muscle, overstretching and overtraining.
- DOMS is prevented/minimized by reducing the eccentric component of muscle actions during early training, starting training at a low intensity and gradually increasing the intensity, and warming up before exercise, cooling down after exercise.
