Cat Muscles - Origin, Insertion, Action

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. 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.

A muscle that can move its point of origin towards its point of insertion. Muscles usually move their insertion towards their origin.

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 insertion then, is the attachment of a muscle on the more moveable bone. The action of the muscle describes what happens when the more mobile bone is brought toward the more stable bone during a muscular contraction. But which is the more stable bone and which is the more moveable bone? The truth is, there are many examples where there is not one single answer to that question. Conventionally, the more stable bone and the more mobile bone are identified with the understanding that the body is in anatomical position.

List of skeletal muscles of the human body

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. Pattern 3 was the most frequently observed pattern

Introduction

 Может быть, хочешь воды. Она не нашлась что ответить. И проклинала. Как я могла не выключить монитор. Сьюзан понимала: как только Хейл заподозрит, что она искала что-то в его компьютере, то сразу же поймет, что подлинное лицо Северной Дакоты раскрыто. И пойдет на все, лишь бы эта информация не вышла из стен Третьего узла. А что, подумала Сьюзан, если броситься мимо него и побежать к двери.

Сьюзан посмотрела на. Сидя рядом с великим Тревором Стратмором, она невольно почувствовала, что страхи ее покинули. Переделать Цифровую крепость - это шанс войти в историю, принеся громадную пользу стране, и Стратмору без ее помощи не обойтись. Хоть и не очень охотно, она все же улыбнулась: - Что будем делать. Стратмор просиял и, протянув руку, коснулся ее плеча. - Спасибо.

Тремя этажами ниже дрожали и гудели резервные генераторы. Сьюзан знала, что где-то на дне этого погруженного в туман подземелья есть рубильник. Кроме того, она понимала, что времени почти не оставалось.
