What is the quiescent centre?

The Quiescent Centre is a group of cells, up to 1,000 in number, in the form of a hemisphere, with the flat face toward the root tip. It is a region in the apical meristem of a root where cell division proceeds very slowly or not at all, but the cells are capable of resuming meristematic activity should tissue surrounding them be…

What is the function of the quiescent Center in roots?

Root Structures and Their Functions: Quiescent Center: behind the root cap is the quiescent center, a region of inactive cells. They function to replace the meristematic cells of the rootcap meristem. The quiescent center is also important in organizing the patterns of primary growth in the root.

What is the difference between quiescent centre and derivative of QC?

Quiescent centre maintains a strict boundary in closed meristem. As a result the derivatives of QC also maintain a strict boundary in the apical zone. Quiescent centre consists of central cells only or central cell and part of its peripheral zones. It does not include the mother cells of columella.

What causes quiescence in plant cells?

Quiescence is caused due to the presence of root cap and the pressure exerted by the dividing initial cells. Cells of QC maintain a long period in the presynthesis (G 1) phase of mitotic cycle and thus they may escape injury. Earlier literatures emphasized regarding the presence and functioning of initiating layers in the root tips of seed plants.

5. Brainstem Respiratory Centers – Pathway Medicine

The Expiratory Center is located in the ventrum of the medulla and appears to primarily activate the rectus abdominus and other expiratory muscles detailed in breathing biomechanics. The expiratory center is normally quiescent during quiet breathing but can be activated by intense stimulation of the inspiratory center, thus providing active expiration of the lungs when …

MeSH. D012125. Anatomical terminology. The respiratory center is located in the medulla oblongata and pons, in the brainstem. The respiratory center is made up of three major respiratory groups of neurons, two in the medulla and one in the pons. In the medulla they are the dorsal respiratory group, and the ventral respiratory group.
