False about funny current channel in hea
Funny / leaky Na+ channels: - Hyperpolarization activated cyclin nucleotide gated (HCN) channels. More the hyperpolarization more the activation Equally permeable for Na+ & K+ After repolarization occur by K+ exit in pacemaker cells, next depolarization spontaneously reaches threshold, major pa in this spontaneous depolarization is by Na+ funny channel.
It is a Na-K ATPase pump
They are responsible for diastolic depolarization
It is responsible for spontaneous rhythm producing tissue of hea
They are voltage dependent channel only
