Below are the events that occur during continuous propagation of action potential. Select the correct order in which the events occur.1. Adjacent membrane segment depolarizes.2. Local current spreads to adjacent voltage gated channel.3. Threshold is met.4. Local current develops due to sodium moving in the cytosol.

Figure 12-2 The Nerve Action PotentialUse Figure 12-2 to answer the following questions:Which area of the graph shows when membrane potential approaches the potassium equilibrium potential?

List the steps involved in fracture repair, beginning just after the fracture occurs.

Fill in the blanks in the Calcium feedback loop below: (normal blood calcium level is 9-11 mg/dL) Stimulus Blood calcium level of 15 mg/dL Receptor/Integrator [Integrator] Hormone Released [Hormone] Effector [Effector] Response [Response] Result [Result] This question will be auto graded by canvas but I will recheck it for answers that are correct but not a perfect match for wording so may be marked incorrect.

________ cells, which differentiate into osteoblasts, are located in the endosteum and inner cellular layer of the periosteum.

The following are major steps in the process of intramembranous ossification.1. Woven bone and periostium begin to form radiateing out from the ossification centers.2. Osteoblasts differentiate within mesenchymal connective tissue forming osteoid to calcify the bone.3. Lamellar bone (compact and spongy) replaces woven bone.4. Mesenchymal cells aggregate thickening and forming ossification centers.What is the correct order for these events?

Figure 6.1Using Figure 6.1, match the following bone types with the numbered structure: (Flat, Long, Irregular, Short, Sesamoid)Bone 5.
