Answer:
From superior to inferior;
1) Femoral
2)Sural
3) Popliteal
4)Tarsal
5) Calcaneal
Explanation:
1) Pertaining to the thigh is the femoral region. The femoral region derives its name from the femur which is a long bone present in the thigh region. The head of the femur articulates proximally with the hip bone at the hip joint or acetabulofemoral joint. The distal end of the femur articulates at the knee joint. The femoral region also has several other structures like the hamstring muscles and the femoral artery.
2) Pertaining to the calf is the sural body region. The calf the region behind the leg. It has several structures like the tibia and fibula bones and the gastrocnemius, soleus and plantaris muscles.
3) Pertaining to the heel is the calcaneal body region. The calcaneus is a big bone located in the posterior part of the foot. It is also called the heel bone. A major attachment to it is the Achilles tendon.
4) Pertaining to the back of the knee is the popliteal body region. The popliteal region is like a cavity made by surrounding muscles of the thigh and calf. It contains the popliteal artery and veins and several nerves running through it.
5) Pertaining to the ankle is the tarsal body region. The tarsal region contains tarsal bones which articulate with each other.
B) humans are more closely related to chimps
Asexual reproduction is usually faster and uses less energy than sexual reproduction. But asexual reproduction produces no differences in DNA among offspring, and creates competition for resources. Sexual reproduction produces differences in the DNA of offspring, and competition for resources is not as high. But sexual reproduction can require a lot more time and energy.
Answer:
1. Water
2. Sodium
3. Posterior
4. Reabsorb
5. Volume
Explanation:
1. ADH or anti-diuretic hormone is the hormone which maintains the level of water in the body as ADH helps in reabsorption of water in the kidney and produces concentrated urine.
2. During dehydration, the level of the water in the blood declines but the concentration of sodium ions increases which increases the osmolarity of the blood.
3. The increased osmolarity are sensed by the osmoreceptors which send the signals to the hypothalamus which stimulates the posterior pituitary to release the ADH or vasopressin hormone.
4. The ADH hormone binds the ADH receptors in the collecting tubule of the kidney which opens the aquaporins to reabsorb the water from the urine.
5. This process in negative feedback as the volume of the blood and osmolarity returns to the normal. Once the level is normal, sends the signals to inhibit the synthesis of ADH from the posterior pituitary.
