Question
**Understanding Muscle Length/Tension Relationships** **Question:** Which of the following are true regarding length/tension relationships in muscle? 1. In the **sarcomere**, the maximal tension occurs at normal resting length. 2. In the **whole muscle**, maximal **passive** tension occurs at ½ normal length. 3. In the **whole muscle**, maximal **active** tension occurs at normal resting length. 4. All of the above 5. Only A and C **Correct Answer:** - Only A and C This question assesses the understanding of how muscle tension varies with changes in muscle length. The sarcomere, the fundamental unit of muscle contraction, reaches maximal tension at its normal resting length. Similarly, the whole muscle achieves maximal active tension at this resting length, allowing for optimal overlap of actin and myosin filaments essential for muscle contraction.
