Glutamate transporter. Glutamate transporters are a family of neurotransmitter transporter proteins that move glutamate â the principal excitatory neurotransmitter â across a membrane. The family of glutamate transporters is composed of two primary subclasses: the excitatory amino acid transporter (EAAT) family and vesicular glutamate transporter (VGLUT) family.
Also known as the bulbourethral glands, are located on either side of the urethra just below the prostate gland and their ducts open into the urethra. They secrete thick mucus acting as a lubricant.he ejaculatory duct in the seminal vesicles passes through the prostate gland and enters the urethra. Glands located at the base of the urinary bladder, opening into the vas deferens as it joins the urethra.
Bulbourethral Glands. The paired bulbourethral (Cowper's) glands are small, about the size of a pea, and located near the base of the penis. A short duct from each gland enters the proximal end of the penile urethra. In response to sexual stimulation, the bulbourethral glands secrete an alkaline mucus-like fluid.he accessory glands of the male reproductive system are the seminal vesicles, prostate gland, and the bulbourethral glands. These glands secrete fluids that enter the urethra.
