Question
The cervical vertebra can usually be distinguished from other vertebrae ty the presence a. Transverse processes b. Transverse foramina Demítacets on the centrum d The vertebra prominens e Large spinous processes 8. The functional or physiological unit of a skeletal muscle fber is the Sarcolemma Sarcoplasmic reticulum d. Myofibri Myofilament 9. The delicate connective tissue that surrounds the skeletal muscle fibers and ties adjacent muscles fibers together is the a. Endomysium b. Perimysium C Epimysium d. Superficial fascia e. Periosteum 10. The skeletal muscle complex known as the triad consists of a. Actin, myosin, and myofilaments b. Transverse tubule and pair of terminal cisternae of sarcoplasmic reticulum c. Myofilaments, myofibrils, and sarcomeres d. A bands, H bands, and I bands e. Actin, myosin, and sarcomeres 11. The type of contraction represented by a single stimulus/contraction/relaxation sequence is a a. Twitch b. Incomplete tetanus c Complete tetanus d. Summation e. Incomplete summation 12. A joint formed by the complete fusion of two bones (with no markings) is a() a. Gomphosis b. Synchondrosis c. Synostosis d. Symphysis e. Diarthrosis 13. When seated, the weight of the body is borne by the a. Ischial tuberosities b. Posterior inferior iliac spines c Iliac crests d. Obturator foramina e. Inferior rami of the pubisExplanation / Answer
7) not visible
8) B- sarcomere
Sarcomere is the functional or physiological unit of skeletal system.myofibrils are composed of actin and myosin filaments in a repetition units called sarcomeres.
They give straited appearance to the skeletal muscle.
9)B- perimysium
Endomysium covers each mucle fibre.
Perimysium covers a bundle of muscle fibre called a fascicle.
Epismysium covers a bundle of fascicles,is a large layer around muscle.
10)B- transverse tubule with two cisternae of sarcoplastic reticulum
It is considered as triad of skeletal muscle complex. As the Car+ released here are basis for muscle movement.
11)A- Twitch
It is a sudden jerk movement caused by sudden,single contraction.
