Put these in order for the muscle contraction process

ca^2+pumps restore cato sr → relaxation!
action potential travels down the axon in response to nerve
stimulus.
(myosin binds to actin
action potential causes caat release from sr
myosin pulls actin chain along and sarcomere shortens
contraction!
action potential travels down the t tubule and into
sarcoplasmic reticulum (sr)
ca^2+binds to troponin. troponin moves tropomyosin
uncovering myosin binding site on actin

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.

loss of sensation to pressure and touch

the dorsal column–medial lemniscus pathway (dcml) (also known as the posterior column-medial lemniscus pathway (pcml)) is a sensory pathway of the central nervous system that conveys sensations of fine touch, vibration, two-point discrimination, and proprioception (position) from the skin and joints.
