Cell Division - Concepts

Cell division is fundamental to all living organisms and required for growth and development. As an essential means of reproduction for all living things, cell division allows organisms to transfer their genetic material to their offspring. For a unicellular organism, cellular division generates a completely new organism. For multicellular organisms, cellular division produces new cells for the general development of the organism, as well as produces healthy cells to replace damaged cells from...

Observing the Cell Cycle in a Root Tip ExpandHypotheses: The experimental hypothesis is that in root tips slices that have been treated with nocodazole, a chemical that interferes with microtubular polymerization, all of the cells will be arrested at the same stage of the cell cycle and that in untreated onion tip slices all of the different stages of the cell cycle will be visualized. The null hypothesis is that there will be no differences in mitosis between the two groups and that different...

Source: Robert E. Sallis, MD. Kaiser Permanente, Fontana, California, USA Examination of the neck can be a challenge because of the many bones, joints, and ligaments that make up the underlying cervical spine. The cervical spine is composed of seven vertebrae stacked in gentle C-shaped curve. The anterior part of each vertebra is made up of the thick bony body, which is linked to the body above and below by intervertebral discs. These discs help provide stability and shock absorption to the...

An Introduction to Cell Division

2023
Cell division is the process by which a parent cell divides and gives rise to two or more daughter cells. It is a means of reproduction for single-cell organisms. In multicellular organisms, cell division contributes to growth, development, repair, and the generation of reproductive cells (sperms and eggs). Cell division is a tightly regulated process, and aberrant cell division can cause diseases, notably cancer. JoVE's Introduction to Cell Division will cover a brief history of the landmark...

This article presents laparoscopic central pancreatectomy with pancreatic duct end-to-end anastomosis as an important surgical approach for middle-segment pancreatic benign and low-grade malignant tumors.
FAQs
Dividing near the portal venous axis helps separate the pancreatic head from the tissue that will remain in the body and tail. In pancreaticoduodenectomy, this supports removal of the diseased head while preserving the distal gland when appropriate. The division therefore serves both as a resection boundary and as a means of retaining tissue that may contribute to later endocrine and exocrine function.
Identifying the main pancreatic duct at the cut surface is important because pancreatic secretions can escape from the divided gland. Control of that surface, followed by reconstruction of drainage or closure of the remnant, is intended to limit pancreatic juice leakage. This matters clinically because leakage can contribute to a postoperative pancreatic fistula, a key complication associated with transection.
The functional consequence depends partly on how much pancreatic tissue remains after the head is removed. Preserving the body and tail retains distal pancreatic tissue for subsequent assessment of endocrine and exocrine function, whereas loss of additional tissue reduces the available remnant. Thus, the division establishes which tissue remains available for postoperative functional evaluation.
Within a pancreaticoduodenectomy, the surgeon divides the gland near the portal venous axis, examines the transected surface to identify the main duct, and then controls the cut surface. The operation proceeds by either reconstructing pancreatic drainage or closing the remnant, depending on the planned surgical management. This sequence links tissue separation with management of pancreatic secretions.
Outcome is influenced by the quality of cut-surface control and by whether pancreatic drainage is reconstructed or the remnant is closed. These choices address the same immediate hazard: pancreatic juice escaping from the divided gland. Attention to this step is especially important because leakage can develop into a postoperative pancreatic fistula, a recognized complication of pancreatic surgery.
Pancreatic neck division is most relevant when surgery must remove the pancreatic head while retaining the distal gland, particularly during pancreaticoduodenectomy. It provides a boundary between diseased and retained tissue for operative management. Afterward, clinicians can assess the residual gland in relation to endocrine and exocrine function, making the maneuver relevant to both resection planning and postoperative evaluation.
