Sinoatrial node  part of the autonomic nervous system adjusts the heart rate and the arteriole diameter to regulate blood pressure through negative feedback

The SA (sinoatrial) node is generates an electrical signal that can causes the upper heart of the chambers (atria) to contract. The signal and then passes through the AV (atrioventricular) node to the lower of the heart chambers (ventricles), causing them to contract, or to pump. The SA node is considered the pacemaker of heart.

The sinus node continuously generates electrical impulses, thereby setting the normal rhythm and also rate in a healthy heart. Hence, the SA node is also referred to as the natural pacemaker of the heart

The footplate of the stapes rests against the _______________, a membrane that marks the entrance to the inner ear.
yuradex [85]

The footplate of the stapes rests against the oval window, a membrane that marks the entrance to the inner ear.

The oval window, also known as the fenestra ovalis, is a connective tissue membrane located at the tip of the center ear and also the beginning of the inner ear.

The oval window is the intersection of the center ear with the sense organ and is directly contacted by the stapes; by the time vibrations reach the fenestra, they need been amplified over 10 times from what they were once they contacted the tympanum, a testament to the amplifying power of the center ear.

The variability of the size of the oval window in one human cadaveric study showed wide variation from 1.26 to 2.40 mm

Give three processes that may cause tectonic plates to move
madam [21]
Thermal Convection, ridge push and slab pull are believed to be the processes that cause plate tectonics to move. Thermal convection is a process when the core of the Earth’s heat is transferred to Earth’s surface by mantle. Ridge push is when the mantle wells upward due to convection and raises the edge of spreading oceanic plates. Since the plates are higher at the spreading center, they are forced downhill because of gravity as a result, the ocean floor is flatten. Slab pull is the part of tectonic plates’ motion which can be accounted for through its subduction.
