Joints
-
Match List-I (Type of Joint) with List-II (Found between).
Pick the matching item from Column II for each row.
Column I
- A. Cartilaginous Joint
- B. Ball and Socket Joint
- C. Fibrous Joint
- D. Saddle Joint
Column II
- I. Between flat skull bones
- II. Between adjacent vertebrae in vertebral column
- III. Between carpal and metacarpal of thumb
- IV. Between Humerus and Pectoral girdle
Correct answer: A → II, B → IV, C → I, D → III
Fibrous joints are between skull bones; saddle joints are between carpal and metacarpal of the thumb.
Cartilaginous Joints – Between adjacent vertebrae in vertebral column. Ball and socket Joint – Between humerus and pectoral girdle. Fibrous Joint – Between flat skull bones. Saddle Joint – Between carpal and metacarpal of thumb.
Muscle – Structure of Contractile Proteins
-
Which of the following statements are correct regarding skeletal muscle? A. Muscle bundles are held together by collagenous connective tissue layer called fascicle. B. Sarcoplasmic reticulum of muscle fibre is a store house of calcium ions. C. Striated appearance of skeletal muscle fibre is due to distribution pattern of actin and myosin proteins. D. M line is considered as functional unit of contraction called sarcomere. Choose the most appropriate answer from the options given below:
The sarcoplasmic reticulum stores calcium, and striations arise from actin-myosin distribution.
Fascicle (muscle bundles) are formed by many muscle fibres and covered by perimysium and all of it held by epimysium. The thick filaments in A-band are also held together in the middle of this band by a thin fibrous membrane called M-line.
