Hi,

Can skeletal muscle be inhibited? I thought I remembered reading somewhere that it could not be inhibited. But then I was looking at the knee jerk reflex and noticed that the hamstring muscles are inhibited during this reflex...so I am confused. Can anyone help?

Thanks

Yes. But two things to note:

a) Skeletal muscle does get hormonal stimulation (has receptors for hormones), but hormones do not affect contraction.
b) Nerve that synapses on skeletal muscle can be inhibited -- in that case, muscle gets no signal and does not contract. Nerve to muscle can get an inhibitory signal, but muscle itself cannot.

Thanks Slight Smile That's what I was thinking, but I wasn't sure.
