What is the purpose of navicular fossa?
We propose that the “fossa navicularis” and “septum glandis” play a role as ‘flow control chamber” in controlling the flow of the urine exiting the urethra, which must be taken into account for successful functional reconstruction of hypospadias.
What is the name of the urethral opening?
From your two kidneys, two ureters move the urine to the bladder, where it’s stored until you urinate (pee). Urine leaves your body through a hole at the end of your urethra. That hole from the inside to the outside is called the urethral meatus. (The term ‘meatus’ refers to any opening from the inside to the outside.)
What makes up the posterior urethra?
The posterior urethra is composed of the membranous and prostatic urethra.
Which region of the male urethra passes through the urogenital diaphragm?
The membranous urethra traverses the urogenital diaphragm. It is the shortest portion of the urethra but the area most vulnerable to injury. The bulbous urethra extends from the bottom of the urogenital diaphragm to the suspensory ligament of the penis.
Where is navicular?
Foot
The navicular bone is one of the seven bones which make up the tarsus of the Ankle and Foot. It is located on the medial aspect of the foot, next to the cuboid bone, anterior to the head of the talus and posterior to the cuneiform bones. It is one of the five bones of the midfoot.
What is urethral orifice?
The internal urethral orifice is the opening of the urinary bladder into the urethra.
What is the epispadias?
Epispadias is a rare birth defect located at the opening of the urethra. In this condition, the urethra does not develop into a full tube, and the urine exits the body from an abnormal location. The causes of epispadias are unknown. It may be related to improper development of the pubic bone.
What is posterior urethra valve?
Posterior urethral valves (PUV) are obstructive membranes that develop in the urethra (tube that drains urine from the bladder), close to the bladder. The valve can obstruct or block the outflow of urine through the urethra.
Are there valves in the urethra?
The urethra is the tube that drains urine from the bladder to the outside of the body. These valves are small leaflets of tissue in the urethra. They partly block urine flow because not enough urine can get through them to leave the body. This causes a reverse flow of urine.
What’s a navicular?
The navicular bone is a small flattened bone, which lies across the back of the coffin joint. It attaches to the pedal bone via a short strong ligament (the impar ligament) and to the pastern joint by ‘suspensory’ ligaments.
What connects to navicular?
The only muscle attachment on the navicular is the tendon of the tibialis posterior. This a muscle located within the deep compartment of the posterior aspect of the tibia and the tendon extends inferiorly around the medial malleolus to insert on the navicular tuberosity.
How should a woman pee properly?
So, step-by-step, the correct way to urinate is:
- Take your time.
- Sit all the way down and do not hover.
- You can lean slightly forward at a 90-degree angle.
- Use a stool to place your feet on if needed (the 90-degree angle at your knees).
- Belly breathe and relax your pelvic floor muscles.
What is exstrophy of cloaca?
Cloacal exstrophy is a condition where some internal organs that are normally in the lower abdomen are exposed externally. In addition, some of these organs may not have developed correctly and the lower parts of the reproductive, urinary and intestinal tracts may not be completely formed.
