The uterus is a hollow, thick-walled muscular organ in the female pelvis that supports menstruation, implantation, and fetal development. Its anatomy includes the fundus, body, isthmus, and cervix, supported by a complex of uterine ligaments and the pelvic floor.
The female urethra is a short muscular tube approximately 3–4 cm long, extending from the internal urethral orifice to the external urethral meatus in the vaginal vestibule. Its close relationship to the anterior vaginal wall and the rhabdosphincter mechanism are critical in urinary continence and gynecological surgery.
The male urethra is approximately 20 cm long and serves both urinary and reproductive functions. It is divided into four parts: intramural, prostatic, membranous (external sphincter), and spongy (penile). The membranous urethra is the narrowest and most vulnerable segment, frequently injured in pelvic trauma.

The basal ganglia are a group of subcortical nuclei including the striatum, globus pallidus, subthalamic nucleus, and substantia nigra. They form key circuits modulating motor control, procedural learning, and reward processing. Dysfunction underlies Parkinson's disease, Huntington's disease, and other movement disorders.
