Navigating Urinary Release: Exploring Micturition in a Visual Mind Map
Delve into the intricate process of micturition with our detailed mind map. Visualize the neural pathways, muscle contractions, and hormonal regulation that control the urinary bladder and urethra.
Understand the role of the brain, spinal cord, and peripheral nerves in initiating and maintaining urination.
Here is a detailed comprehensive mind map of the physiology topic “Micturition”:
Central Idea: Micturition
Main Branches:
- Neural Control of Micturition
- Physiology of Micturition
- Regulation of Micturition
- Disorders of Micturition
- Clinical Correlations of Micturition
Sub-branches:
Neural Control of Micturition
- Brain Centers Involved
- Pontine micturition center (PMC)
- Cerebral cortex (suprapontine centers)
- Spinal Cord Reflexes
- Micturition reflex (sacral micturition center)
- Inhibitory reflexes (sympathetic and somatic)
- Neurotransmitters and Receptors
- Acetylcholine (ACh) and muscarinic receptors
- Norepinephrine (NE) and adrenergic receptors
Physiology of Micturition
- Urinary Bladder Function
- Storage phase (relaxation and accommodation)
- Voiding phase (contraction and expulsion)
- Urethral Function
- Urethral sphincter (internal and external)
- Urethral pressure profile
- Micturition Reflex
- Afferent pathway (sensory fibers)
- Efferent pathway (motor fibers)
Regulation of Micturition
- Voluntary Control
- Cortical control (suprapontine centers)
- Pontine control (PMC)
- Autonomic Control
- Sympathetic nervous system (inhibitory)
- Parasympathetic nervous system (excitatory)
- Hormonal Regulation
- Vasopressin (antidiuretic hormone, ADH)
- Oxytocin (uterotonic and milk letdown)
Disorders of Micturition
- Urinary Incontinence
- Stress incontinence
- Urge incontinence
- Overflow incontinence
- Urinary Retention
- Acute urinary retention
- Chronic urinary retention
- Neurogenic Bladder Dysfunction
- Spinal cord injury
- Multiple sclerosis
- Parkinson’s disease
Clinical Correlations of Micturition
- Urodynamic Studies
- Cystometry
- Urethral pressure profilometry
- Electromyography (EMG)
- Micturition Disorders in Special Populations
- Pediatric population
- Geriatric population
- Neurological disorders (e.g., spinal cord injury, multiple sclerosis)
- Therapeutic Interventions
- Pharmacological therapy (e.g., anticholinergics, alpha-blockers)
- Surgical interventions (e.g., bladder neck incision, urethral dilation)
This mind map provides a comprehensive overview of micturition, including the neural control of micturition, physiology of micturition, regulation of micturition, disorders of micturition, and clinical correlations of micturition.
It highlights the various aspects of micturition and their interconnections.
