LEAVE ACCRUAL RECORDS. Vacation and sick leaves are accrued based on the leave accrual codes established on the Payroll Personnel System (PPS). Leave code is established by the department when an appointment is initially set up. For staff employees thereafter, the PPS will re-derive the leave code on the appointment during month-begin periodic maintenance.
For muscles to contract there needs to be an adequate supply of ATP within the cell. ATP is generated in part by a supply of glucose and oxidative phosphorylation. An inadequate supply of blood will not provide enough oxygen to keep up with the energy demands of contraction.
Muscular arteries distribute blood to the skeletal muscles and internal organs. The tunica media of the muscular arteries have a higher percentage of smooth muscles than connective tissue. Vasoconstriction and vasodilation of these vessels is controlled by the autonomic nervous system.ontraction of the smooth muscles of the media is called vasoconstriction and results in a decrease in the size of the lumen and a decrease in blood flow. Relaxation of the smooth muscles is vasodilation which has the opposite effects.
