- https://med.libretexts.org/Bookshelves/Veterinary_Medicine/Anatomy_and_Physiology_of_Animals_(Lawson)/07%3A_Muscles/7.03%3A_Smooth_MuscleThere are three different kinds of muscle tissue: smooth muscle in the walls of the gut and blood vessels; cardiac muscle in the heart and skeletal muscle attached to the skeleton.

Figure \PageIndex1: Muscle Tissue. (a) Skeletal muscle cells have prominent striation and nuclei on their periphery. (b) Smooth muscle cells have a single nucleus and no visible striations. (c) Cardiac muscle cells appear striated and have a single nucleus.

The SNS connects motor neurons directly to skeletal muscles, while the ANS uses a two-neuron chain for cardiac and smooth muscles and glands. Efferent pathways also differ: SNS utilizes lower motor neurons for somatic reflexes, whereas the ANS employs preganglionic and postganglionic neurons for visceral reflexes.

It details the three types of muscle: skeletal (striated, voluntary), cardiac (rhythmic, involuntary), and smooth (non-striated, regulates internal movements), noting their unique characteristics and shared properties like excitability and dependence on ATP for contraction.

While it offers high-resolution images, its high radiation exposure and cost are limitations. Innovations like peripheral quantitative CT (pQCT) seek to minimize radiation while assessing bone health. CT is becoming more important in studying sarcopenia, but the absence of clear diagnostic standards hampers its clinical use.

All three muscle tissues have some properties in common; they all exhibit a quality called excitability as their plasma membranes can change their electrical states (from polarized to depolarized) and send an electrical wave called an action potential along the entire length of the membrane.

It highlights the technology's ability to detect minor body composition changes and the reduction in scan times from 10 minutes to under 2 minutes. While effective in distinguishing adipose from lean tissue through hydrogen nuclei behavior, it requires technical expertise and can be expensive.

The lateral collateral ligament is on the lateral side of the knee and spans from the lateral side of the femur to the head of the fibula. Acting via the patella and patellar ligament, the quadriceps is a powerful muscle that extends the leg at the knee and provides support and stabilization for the knee joint.
