Question
The body temperature in humans is maintained around 37 degree C. Which characteristic of life does this statement represent? A. Living things utilize materials and energy from the environment. B. Living things are homoeostatic C. Living things are adapted D. Living things grow and develop E. Living things respond to stimull. The cervical vertebra can usually be distinguished from other vertebrae by the presence of A. Transverse processes B. Transverse foramina C. Demifacets on the centrum D. The vertebra prominens E. Large spinous processes The functional unit of a skeletal muscle fiber is the A. Sarcolemma B. Sarcomere C. Sarcoplasmic reticulum D. Myofibril E. Myofilament The delicate connective tissue that surrounds the skeletal muscle fibers and ties adjacent muscle fibers together is the A. Endomysium B. Perimysium C. Epimysium D. Superficial fascia E. Periosteum The skeletal muscle complex known as the triad consists of A. Actin, myosin, and myofilaments B. Transverse tubule and terminal cistema C. Myofilaments, myofibrils, and sarcomeres D. A bands, H bands, and I bands E. Actin, myosin, and sarcomeresExplanation / Answer
16. The hypophyseal fossa or Sella turcica contains B. Pituitary gland.
17. Maintenance of body temperature at 370 C is stated in the option: B. Living things are Homeostatic. This is a very important function, as some of the living species are warm blooded and some are cold blooded, so the mechanism that stabilizes the temperature outside and inside to form and keep us at a steady state is that homeostatic mechanism. To make body temperature in 370 C for humans, if its drops down it starts to shiver and keep it up to again normal.
18. The cervical vertebra can usually be distinguished from others vertebrae by the presence of B. Transverse Foramina. This is an opening that is present only in the cervical vertebra for the passage of the vertebral artery and vein and the sympathetic nerve plexus.
19. Functional unit for the skeletal muscle fiber is the B. Sarcomere, this is the basic unit where the repeated Z lines are present and it contains all other parts like a protective layer Sarcolemma, inside is Sarcoplasmic reticulum, also there are firbillar structures.
21. The skeletal muscle complex known as the triad consists of a B. Transverse tubule with a sarcoplasmic reticulum (SR) known as the terminal cisterna on either side. Visible in muscle cells fibers and been sectioned to see the thousands of triads that are present.20. The delicate connective tissue that surrounds the skeletal muscle fibers and ties adjacent muscle fibers together is the A. Endomysium, this means within the muscle.
