The following sections describe the normal development of the urinary system. Under each section heading are the desired learning objectives for that section.
The following
discussions follow a logical progression. It is strongly recommended
to follow the prompts at the end of each section.
- Early
kidney development
Objectives
- To identify the three stages of kidney development and give characteristics of each of the stages
- To list the adult derivatives of the embryonic structures of each of the early kidney stages
- Development
of metanephros (kidney proper)
Objectives
- To explain the formation of the mature kidney from its embryonic origins
- To name an anomaly which may result from a failure of proper development of the ureteric bud
- Development
of metanephros (cont.)
Objectives
- To describe the development of the nephron from aggregation of mesenchyme to fully developed functional unit
- To describe at least one theory for the development of a polycystic kidney
- Ascent of
the kidneys
Objectives
- To describe the ascent of the kidneys including changes to arterial blood supply
- To name at least one anomaly which can result from a failure of the kidneys to ascend
- Development
of the Urinary Bladder
Objectives
- To list the three components of the uro-genital sinus and describe their adult derivatives
- To explain the formation of the urinary bladder proper
- To describe the destiny of the mesonephric ducts in both the male and female embryo
- To explain the origin of the umbilical ligaments
