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.

Muscles of Facial Expression

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

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. The first grouping of the axial muscles you will review includes the muscles of the head and neck, then you will review the muscles of the vertebral column, and finally you will review the oblique and rectus muscles. The muscles of facial expression originate from the surface of the skull or the fascia connective tissue of the face. The insertions of these muscles have fibers intertwined with connective tissue and the dermis of the skin.

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.

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?

muscles- origins/ insertion & actions

То, что она увидела, казалось лишенным всякого смысла. 22: РУЧНОЕ ОТКЛЮЧЕНИЕ ГЛАВА 35 Беккер в шоке смотрел на Росио. - Вы продали кольцо. Девушка кивнула, и рыжие шелковистые волосы скользнули по ее плечам.

Мы будем ждать. Джабба открыл рот. - Но, директор, ведь это… - Риск, - прервал его Фонтейн.  - Однако мы можем выиграть.  - Он взял у Джаббы мобильный телефон и нажал несколько кнопок.

 - Скажем, принести пару таблеток валиума. Наконец канадец опомнился. - Из консульства? - Его тон заметно смягчился.

The muscle groups and their actions

Агенты связались с ним, когда он находился в Южной Америке, и сообщили, что операция прошла неудачно, поэтому Фонтейн в общих чертах уже знал, что случилось. Тут вступил агент Колиандер: - Как вы приказали, мы повсюду следовали за Халохотом. В морг он не пошел, поскольку в этот момент напал на след еще какого-то парня в пиджаке и галстуке, вроде бы штатского. - Штатского? - переспросил Фонтейн. Скорее всего это игры Стратмора: он мудро решил не впутывать в это дело агентство. - Фильтры Протокола передачи файлов выходят из строя! - крикнул кто-то из технического персонала. - Нам нужен этот предмет, - сказал Фонтейн.

Сьюзан застыла в полутора метрах от экрана, ошеломленная увиденным, и все называла имя человека, которого любила. ГЛАВА 115 В голове Дэвида Беккера была бесконечная пустота. Я умер. Но я слышу какие-то звуки. Далекий голос… - Дэвид. Он почувствовал болезненное жжение в боку.

PRIME DIFFERENCE BETWEEN ELEMENTS RESPONSIBLE FOR HIROSHIMA AND NAGASAKI ГЛАВНАЯ РАЗНИЦА МЕЖДУ ЭЛЕМЕНТАМИ, ОТВЕТСТВЕННЫМИ ЗА ХИРОСИМУ И НАГАСАКИ - Это даже не вопрос! - крикнул Бринкерхофф.  - Какой же может быть ответ. - Нам необходимо число, - напомнил Джабба.  - Шифр-убийца имеет цифровую структуру. - Тихо, - потребовал Фонтейн и повернулся к Сьюзан.

 А неприятности немалые.

 Но… офицер ничего не сказал о… - Разумеется. Я не сказал ему про спутницу.  - Взмахом руки Клушар величественно отверг вопрос Беккера.  - Они не преступницы - глупо было бы искать их, как обычных жуликов.

Human muscle system

В сердцах он швырнул трубку на рычаг. - Черт! - Фонтейн снова схватил трубку и набрал номер мобильника Стратмора. На этот раз послышались длинные гудки.
