- Striations are a key attribute to identify skeletal and cardiac muscle types. Although striations are usually visible in most sections of these muscle types, it can sometimes take a little adjustment of the microscope lighting to see them clearly.

7 Layers of Muscle Skeletal muscle tissue is named for its location-attached to bones. It is striated; the fibers (cells) contain alternating light and dark bands (striations) that are perpendicular to the long axes of the fibers.Skeletal muscle tissue can be made to contract or relax by conscious control (voluntary).t is striated; the fibers (cells) contain alternating light and dark bands (striations) that are perpendicular to the long axes of the fibers.

What is Skeletal Muscle? 10 hilariously insightful foreign words. Skeletal muscle is striated muscle tissue that is attached to bones. It is composed of fibers that look like a mixture of dark and light bands bundled together that run along the bone. These muscles are responsible for contracting and relaxing when a person moves.keletal muscle is striated muscle tissue that is attached to bones. It is composed of fibers that look like a mixture of dark and light bands bundled together that run along the bone.

- There are two other types. One is smooth muscle, which has no visible striations and it also involuntary. This is found in arteries and the walls of the digestive, urinary, other hollow organs and respiratory tracts and the irises of the eye.

How Muscles Work Skeletal-muscle Basics. Skeletal muscle is also called striated muscle, because when it is viewed under polarized light or stained with an indicator, you can see alternating stripes of light and dark.Skeletal muscle has a complex structure that is essential to how it contracts.keletal-muscle Basics. Skeletal muscle is also called striated muscle, because when it is viewed under polarized light or stained with an indicator, you can see alternating stripes of light and dark.

- The skeletal muscle, or striated muscle, is the muscle attached to the skeleton. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons …. The contraction of skeletal muscle is under voluntary control.

Why does smooth muscle have no striations? This is true for striated and non-striated muscle. However the smooth muscle, with the high ration of of actin to myosin results in the ability for it to have a much higher elasticity and are able to stretch more than striated muscles.

What is the difference between an endocrine nad exocrine gland? Best Answer: Endocrine glands have no ducts. They secrete what is called hormone. The hormone is released in the blood stream and is circulated in the blood where it finds a particular organ, called target organ, to which goes and influences its physiology.An exocrine gland has duct, which is the conduit for the release of products produced by it.hey secrete what is called hormone.

"""Define The Terms Skeletal Muscle Fiber Motor Unit Skeltal Muscle Twitch"" Essays and Research Papers" There are three types of muscle tissue: skeletal, smooth, and cardiac. Skeletal muscle tissue is a voluntary type of muscle tissue that is used in the contraction of skeletal … parts.It is striated (alternating with light and dark bands, called striations) and is attached to bones.IMPROVED ANSWER:  Skeletal muscle is a type of striated muscle, which usually attaches to tendons. Skeletal muscles are used to create movement, by applying force to bones and joints via contraction.

- Also, striations are only visible in longitudinal views of myofibers so it is essential some part of the muscle section being evaluated includes this type of cut. Remember, striations across cells indicate you are viewing cardiac or skeletal muscle. Differentiation of these two types involves other structural features. We will examine these now! Skeletal muscle is the most abundant muscle type in the body.

- Non-striated Muscle. As the name implies, non-striated muscle lacks visible striations. Smooth muscle is the only muscle of this type and without striations, other less obvious characteristics are used to identify this tissue.Before we examine smooth muscle in longitudinal or cross-section, it might be worth our while to determine why some myofibers are striated while others are not.mooth muscle is found in walls of hollow organs and blood vessels where contractility and stretch are both specific needs. Think of the bladder or the uterus of a pregnant female.
