Abstract
- Intracellular recordings were made from arterioles lying in the submucosa of guinea-pig small intestine. 2. Low frequency perivascular nerve stimulation evoked subthreshold excitatory junction potentials which facilitated. 3. Higher frequency stimulation caused summation of excitatory junction potentials and the initiation of muscle action potentials. 4. Arteriolar constriction was only observed following the initiation of a muscle action potential.
摘要
- 从豚鼠小肠黏膜下层的小动脉进行细胞内记录。2. 低频血管周围神经刺激诱发阈下兴奋性接头电位，该电位具有易化作用。3. 较高频率刺激导致兴奋性接头电位总和并引发肌肉动作电位。4. 仅在肌肉动作电位引发后才观察到小动脉收缩。
