!Penis - Cavernous Bodies
!!Anatomy
The two corpora cavernosa and corpus spongiosum are three __expandable erectile tissues__ along the length of the penis which __fill with ((Circulatory - Blood|blood)) during penile erection__. The two corpora cavernosa lie along the penis shaft, from the pubic bones to the head of the penis, where they join. These formations are made of a sponge-like tissue containing irregular blood-filled spaces which have an inner lining of endothelium.

The arterial cavernous bodies are covered by a layer of strong ((Musculoskeletal - Connective Tissue|connective tissue)), from which the septa extend into the inner part, separating different vascular spaces. This provides the structure for erection of the penis when __drainage of the ((Circulatory - Arteries|arterial)) ((Circulatory - Blood|blood)) is throtteled__. In unaroused state they are exsanguinated. The female equivalent is the corpus cavernosum clitoridis.

The venous corpus spongiosum surrounds the urethra and secures it's patency during erection by elastic fibres. It continues in the bulbous __((Reproductive - Penis - Glans and Foreskin|glans))__, the tip of the penis, where it is covered by a ((Nervous - Sensory Innervation|sensitive)) mucosa.

!!Mind
!!!Theme:
Sexual Self-Worth

!!!Emotions and Thoughts:
__Frustration, self-doubt, self-hate__
*I can´t get/hold him up!
*I can´t make her lucky.
*I can´t satisfy her.
*I´m not worthy as a man.
!!!META-Meaning:
*I totally love and accept myself. 
*I´m feeling confident and at ease with my love. 
*Enjoying soft love makes me feel good.

!!Organ
!!!Stress Phase Symptoms:
Inhibition of the erectile function, later decreased trophic of the cavernous bodies, necrosis. Possible diagnoses: __erectile dysfunction__, impotence, penis atrophy. Micropenis can be caused by inherited patterns and beliefs.

!!!Regeneration Phase A:
Inflammatory swelling & oedema; in combination with ((Urinary - Kidneys - Collecting Tubules|water retention)), __priapism__ is possible.

!!!Regeneration Phase B:
Replenishment, often excessive. fibrous knots can cause pain with erection. Possible diagnoses: __Penis deviation, La Peyronie´s disease__ (Induratio penis plastica) especially in chronic cycles.

!!!Biological Meaning:
The fibrous reinforcement of the tissue in regeneration phase could be meant to enhance and solidify erection.

!!Social
!!!Examples:
*An adolescent wishes to make love but feels disturbed and distracted by memories of his mother telling him about unfaithful men.

*A student living in a commune feels ashamed and afraid of making noises with his sex partner.

*A man meets a sexually active woman in a bar, who touches his private parts. He doesn´t feel turned on but doesn´t want to admit it.

*A young man had an erection in several challenging situations like exams, and became very anxious for this happening. That curbed his potency. After releasing his fears, the reaction normalizes. (Cabral, MHU archive) 
!!Additional Information
__Penile erection__ is the result of a complex interaction of psychological, neural, vascular and endocrine factors, and is often associated with sexual arousal or sexual attraction, although erections can also be spontaneous. The shape, angle and direction of an erection varies considerably in humans.

Physiologically, erection is triggered by the __parasympathetic division__ of the autonomic nervous system (ANS), causing nitric oxide (a vasodilator) levels to rise in the trabecular ((Circulatory - Arteries|arteries)) and ((Organ Walls - Smooth Muscle Layer|smooth muscle)) of the penis. The arteries dilate causing the corpora cavernosa of the penis (and to a lesser extent the corpora spongiosum) to fill with blood; simultaneously the ischiocavernosus and bulbospongiosus muscles compress the veins of the corpora cavernosa restricting the egress and circulation of this blood. Erection subsides when parasympathetic activity reduces to baseline.

!!!Constellations
__Sexual Megalomania__ in both-sided activation as a coping strategy. Compare Casanova-Constellation of coronary vessels or ((Reproductive - Seminal Duct, Prostate Ducts, Seminal Vesicle|seminal vesicles)).

!!!Differential Diagnosis:
__Diabetes__ is seen as a leading cause of erectile dysfunction. (See Pancreas - ((Endocrine - Pancreas - Beta Islet Cells|Beta Islet Cells)))

__Lymphangiosclerosis__ is a hardened __((Circulatory - Lymph-Vessels|lymph vessel))__ (Cerebral Medulla, -/+) in the penis, e g by chronic self-devaluation patterns.

Reduced __libido__ and arousal also happen by neuronal affections, and in stress-activity (loss of love or status) of the ((Circulatory - Coronary Arteries (Intima)|coronary arteries)) / the ((Reproductive - Seminal Duct, Prostate Ducts, Seminal Vesicle|seminal vesicles ))
