Muscle origins and insertions describe the places where a muscle attaches on bones. Conventionally, a muscle origin describes the attachment of a muscle on the more stable bone.

The superior tarsal muscle STM is a smooth muscle that originates from the undersurface of the levator palpebrae superioris muscle LPSM and inserts onto the superior tarsal plate STP of the upper eyelid. We have performed a morphometrical investigation of the STM in 49 adult human cadavers 34 males, 15 females. Accordingly, we describe four patterns of STM.

Human muscle system

Human muscle system , the muscles of the human body that work the skeletal system , that are under voluntary control, and that are concerned with movement, posture, and balance. Broadly considered, human muscle—like the muscles of all vertebrates—is often divided into striated muscle or skeletal muscle , smooth muscle , and cardiac muscle. Smooth muscle is under involuntary control and is found in the walls of blood vessels and of structures such as the urinary bladder , the intestines , and the stomach. Cardiac muscle makes up the mass of the heart and is responsible for the rhythmic contractions of that vital pumping organ; it too is under involuntary control. With very few exceptions, the arrangement of smooth muscle and cardiac muscle in humans is identical to the arrangement found in other vertebrate animals.

Describing Skeletal Muscles: A Review of Muscle Attachments And Actions

By the end of this section, you will be able to identify the following muscles and give their origins, insertions, actions and innervations:. The skeletal muscles are divided into axial muscles of the trunk and head and appendicular muscles of the arms and legs categories. This system reflects the bones of the skeleton system, which are also arranged in this manner. Some of the axial muscles may seem to blur the boundaries because they cross over to the appendicular skeleton.

With very few exceptions, the arrangement of smooth muscle and cardiac muscle in humans is identical to the arrangement found in other vertebrate animals. This article is concerned with the skeletal muscles of the human body, with emphasis on muscle movements and the changes that have occurred in human skeletal musculature as a result of the long evolutionary process that involved the assumption of upright posture. Smooth muscle and cardiac muscle and the physiology of muscle contraction are treated at great length in the article muscle.

Компания связана обязательством ни при каких условиях не раскрывать подлинное имя или адрес пользователя. - Это не доказательство, - сказал Стратмор.  - Но кажется довольно подозрительным. Сьюзан кивнула. - То есть вы хотите сказать, Танкадо не волновало, что кто-то начнет разыскивать Северную Дакоту, потому что его имя и адрес защищены компанией ARA. - Верно.

И они делают их все более и более миниатюрными, - подумал. Прикрыв глаза, давая им долгожданный отдых, он вдруг почувствовал, что кто-то тянет его за ногу. - Джабба. Вылезай скорее! - послышался женский голос. Мидж все же его разыскала.

 Наверное, стоит выключить ТРАНСТЕКСТ, - предложила Сьюзан.  - Потом мы запустим его снова, а Филу скажем, что ему все это приснилось. Стратмор задумался над ее словами, затем покачал головой: - Пока не стоит. ТРАНСТЕКСТ работает пятнадцать часов. Пусть пройдут все двадцать четыре часа - просто чтобы убедиться окончательно.
