Answer:
c. capillary
Explanation:
Capillary -
Capillaries are the small blood vessels with diameter of 5 to 10 micrometres .
In the body , the capillary are the smallest blood vessels .
The main function of capillaries is to exchange substance along with the interstitial fluids .
Substance like , water , glucose , oxygen carbon dioxide , nutrients etc .
Hence , from the information from the question , the answer is capillaries .
<h2>C
arotid Artery</h2>
Also, the jugular vein is separated from deep structures within the carotid sheath by the Omohyoideus m (which acts as a backstop to prevent you from injecting things into the horse's common carotid artery instead of the external jugular vein. It could cause excitability, collapse, brain damage, or death).
Answer:
1. E) During muscle contraction all of the answers above are correct.
2. A) Myosin pulls actin filaments toward the M disk.
Explanation:
The mechanism of muscle contraction is also known as the sliding filament theory. It explains the activities which occur during contraction of muscles.
Muscles are made up of functional units called sarcomeres and these sarcomeres made up of myofibrils which are long and thin strands of protein. Myofibrils contain thin filaments called actin and thick filaments called myosin. Interactions between the thin and thick filaments results in contraction.
The I band contains thin filaments. The H band is the area of no thin filaments. The M line is the midline of the thick filaments. The Z line is the boundary between adjacent sarcomeres and the A band is the area of thick filaments.
Contraction occurs when muscle fibres are activated by neurons through the release of calcium ion. On stimulation, the H and I band get smaller, the zone of overlap gets larger and the Z lines move closer together and the A band remains constant. This the thin filaments slide towards the center resulting in the shortening of the sarcomeres and the muscle fibres as a whole.
The forefoot contains the five toes (phalanges) and the five longer bones (metatarsals). The midfoot is a pyramid-like collection of bones that form the arches of the feet. These include the three cuneiform bones, the cuboid bone, and the navicular bone. The hindfoot forms the heel and ankle.
