Surprisingly, in Tfm males, the effects of EB, DHT, and hydroxyflutamide were all indistinguishable from those observed in wild-type animals. DHT almost doubled the number of synaptic contacts observed, whereas hydroxyflutamide increased synapse density by approximately 50%, compared with the vehicle-injected controls. In wild-type males, DHT and hydroxyflutamide both induced increases in the number of spine synapses in the CA1 stratum radiatum, whereas EB had no effect. d), or the sesame oil vehicle sc daily for 2 d and examined using quantitative electron microscopic stereological techniques, 48 h after the second injection.Orchidectomized rats were treated with EB (10 μg/rat To elucidate the contribution of the androgen receptor to the hormone-induced increase in hippocampal CA1 synapses, wild-type males were compared with males expressing the Tfm mutation, which results in synthesis of defective androgen receptors.

If you’re experiencing back pain, you need to seek the help of a professional.

Because it houses so many important muscles and nerves that then run throughout the body, it requires great care throughout life to prevent discomfort, inflexibility, and disease. The human spine is incredibly intricate and comprises numerous parts. For example, thoracic spinal nerves T1 through T12 branch out beneath the corresponding thoracic vertebrae. A spinal nerves name and a spinal nerves number typically refer to the vertebrae beneath which they are passing. Spinal nerves produce movements, collect sensory information or provide automatic signals from the brainstem to the body.Įvery person has 31 pairs of spinal nerves with half of each set branching out to each side of the body.
