What exhibits autorhythmicity?
Certain types of cardiac muscle cells, such as those found in the sinoatrial (SA) node of the heart, exhibit autorhythmicity. This property allows them to generate spontaneous action potentials without the need for external stimulation. Other examples include some neurons in the brain and pacemaker cells in the digestive system.
Type of muscle that is voluntary and striated?
SKELETAL (:
What muscle tissue is multinucleated?
skeletal muscles
Which muscle is not directly controlled by the autonomic nervous system?
smooth muscle, cardiac muscle and most glands
Which muscle tissue concerns with locomotion of the body as a whole?
Skeletal muscle
What type of muscle is the tricep muscle?
A skeletal muscle.
What you mean by autorhythmicity?
The pacemaker is known as the SA node (sinotrial) and it generates action potentials to the AV node and then to the bundle of his down to the purkinje fibers. The branching of cardiac muscle tissue and the intercalated discs allow action potentials to propagate to other cardiac mt cells. The autorhythmicity of the heart is attributed to the fact that it creates its own action potentials from the SA node and can be generated independently from the rest of the body. The heart's autorhythmicity also prevents it from reaching tetanus (like a skeletal muscle does), because myocardial tissue only allows a certain amount of action potentials through before it reaches its absolute refractory period when it comes to a plateau and after the wave drops again and gets hit with another action potential it has already rested.
What is straited muscle?
straited muscle are another form of skeletal muscle.
What are the feature of skeletal muscle?
The skeletal muscle is heavily stratified
Is the skeletal muscle a smooth muscle?
no skeletal muscles are voluntary smooth muscles are not
What type of tissue is skeletal muscle?
Skeletal muscle is voluntary muscle.
What is a group of skeletal muscle fibers?
A skeletal muscle
