Skeletal muscle tissue differs from cardiac tissue in that skeletal muscles are striated muscles that require conscious stimulation to act, and cardiac muscles are smooth and basically run "automatically".
Uhh, no uncontrolled muscle contraction occurs in smooth and cardiac muscles... there are many differences between these two types of muscles; controlled and uncontrolled muscle contraction.....
A good example to illustrate the relationship between anatomy and physiology is the relationship between how a skeletal muscle is structured (anatomy) and how it works (physiology) to produce a muscle contraction. Skeletal muscles are organized into units called sarcomeres which are overlapping chains of two different proteins, actin and myosin. That in a nutshell is the microscopic anatomy of skeletal muscle. Physiologically how it works is that the myosin heads latch onto the actin chain pulling it into the center of the sarcomere shortening it which causes the contraction.
the connection between the two is like this. the nervous system sends the signal to the skeletal muscle to contract. This contraction causes the muscle to pull the bone, and the bone bends. This would mean that the movement of the skeleton is caused by nervous system which triggers the skeletal muscle to move the skeleton.
cardiac is cardiac and skeletal is skeletal.
Acetylcholine release is necessary for skeletal muscle contraction, because it serves as the first step in the process, enabling the subsequent cross-bridge formation. A muscle's ability to contract depends on the formation of cross-bridges between myosin & actin filaments. A drug that blocks acetylcholine release would interfere with this cross-bridge formation and prevent muscle contraction
As the muscle workload increase, its threshold of stimulation increases.
One key difference between cardiac and skeletal muscles is that skeletal muscles are controlled by the nervous system, while cardiac muscles move involuntarily. In addition, cardiac muscles are only found in the heart, while skeletal muscles are found throughout the entire body.
An Isotonic muscle contraction is a muscle contraction that makes your limbs move whereas an Isometric contraction is a muscle contraction where the limbs stay static
Bone growth stimulation cannot be used if the gap between the ends of the fracture is too large.
the interval between stimulation and response.
