Ch. 9 Muscle and Muscle Tissue Smooth Muscle. Found in walls of most hollow organs(except heart); Usually in two layers (longitudinal and circular); lack coarse connective tissue sheath; smooth muscle fibers SR is less developed then that of skeletal muscle and lacks specific pattern relative to myofilaments (no sacromeres, myofibrils or t tubules). •.

Organ (anatomy) In anatomy, a viscus /ˈvɪskəs/ is an internal organ, and viscera is the plural form. Organs are composed of main tissue, parenchyma, and sporadic tissues, stroma. hollow organ is a visceral organ that forms a hollow tube or pouch, such as the stomach or intestine, or that includes a cavity, like the heart or urinary bladder.

The muscles of the lateral abdominal wall The transverse abdominal muscle (m. transversus abdominis) forms the deepest layer of muscles of the lateral abdominal wall. The muscle is part of the abdominal muscles, flattens the abdominal wall and brings the lower parts of the chest wall.At the top of the muscle starts from the inner surface of the cartilages of six lower ribs, and below-from the iliac crest, inguinal ligament and thoracolumbar fascia.he muscle is broad and flat, part of the abdomen. Start point is on the outer surface of the lower eight ribs. Pencils are sent to the oblique muscles down and in front (to the anterior abdominal wall), turn into aponeurosis.

- 4 - Electric organs. Skeletal muscles have muscular & tendinous portions: 1  Muscle-consists of skeletal muscle cells (which, in turn, consist of myofibrils and myofilaments). 2  Tendons-extensions of a muscle's tough connective tissue sheath (fascia & epimysium) that anchor a muscle to its origin & insertion. - Electric organs.

- These myofilaments are arranged in muscles in two different ways to provide contractility with different capabilities. Smooth 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.To accommodate substantial stretch and still retain contractility, actin and myosin myofilaments are arranged randomly in smooth muscle.mooth muscle is found in walls of hollow organs and blood vessels where contractility and stretch are both specific needs.

- We have the epidermis which is the outer epithelium tissue and dermis is the connective tissue. 2. Mucous (mucosa) membranes line the insides of hollow organs that open to the outside. Three closed cavities: Pleural (lungs), peritoneal (abdominal), and pericardial (heart) cavities.

What type of muscle tissue lines the digestive system organs? Answers. 1  Smooth muscle lines hollow organs, blood vessels, glands, etc. In the gut, there is a circular layer of smooth muscle (for mixing food and enzymes and digestive juices together) and a longitudinal layer of smooth muscle (for propelling food along). Skeletal muscle is attached to bones, or to the body surface (some facial muscles).

Muscles of the Abdomen, Lower Back and Pelvis Muscles of the Abdomen, Lower Back and Pelvis. The muscles of the abdomen, lower back, and pelvis are separated from those of the chest by the muscular wall of the diaphragm, the critical breathing muscle.ull Muscles of the Abdomen, Lower Back and Pelvis Description. Extending across the anterior surface of the body from the superior border of the pelvis to the inferior border of the ribcage are the muscles of the abdominal wall, including the transverse and rectus abdominis and the internal and external obliques.

Anatomy & Physiology Smooth muscle: Found in the walls of hollow organs. Cardiac muscle: Exists only in your heart. Three types of muscle. You've got around 650 muscles in your body, and they make up roughly half of your bodyweight. These muscles can be divided into three different groups: skeletal, smooth and cardiac.

Types of Muscles and Their Functions This type of muscles, as the name suggests are found in the heart. It is intermediate in structure, being striated and at the same time involuntary. It is meant for automatic and rhythmic-contractions and each muscle fiber.isceral muscle is found inside of organs like the stomach, intestines, and blood vessels. Visceral muscles are weakest of all the muscles. Their main function is to move substances through the organ. This type of muscles are also called plain, unstriped, non-striated, visceral, or involuntary muscles.

The muscles of the lateral abdominal wall The muscles of the lateral abdominal wall are the broad muscles of the abdomen and placed in three layers. External oblique muscle belly (m. obliquus externus abdominis) forms a surface layer of the lateral abdominal wall.he muscle is broad and flat, part of the abdomen.

Learn About Muscle Tissue Visceral (Smooth) Muscle. Visceral muscle is found in various parts of the body including blood vessels, the bladder, digestive tract, as well as in many other hollow organs. Like cardiac muscle, most visceral muscle is regulated by the autonomic nervous system and is under involuntary control.

Lungs and Respiratory System of the Chest The muscles of the thoracic cavity, including the diaphragm and intercostal muscles, change the volume of the thoracic cavity to force air into and out of the lungs. The diaphragm is a thin, dome-shaped skeletal muscle that forms the floor of the rib cage between the lungs and abdomen. The diaphragm contracts and pushes itself into the abdominal cavity, increasing the volume of the thoracic cavity and expanding the lungs to draw in fresh atmospheric air. When it relaxes, the diaphragm returns to its original position and forces air out of the lungs during exhalation.

Acoustic-Phonetics Demonstrations The muscles that contribute to quiet breathing are the external intercostal muscles and the diaphragm. (The external and internal intercostals are the muscles that fill the gaps between the ribs.) When drawing breath (i.e., during inspiration), the external intercostal muscles and diaphragm contract simultaneously.uring inspiration, the diaphragm contracts strongly, causing a large expansion of the thorax vertically. At the same time, intra-abdominal pressure increases and causes the abdomen to bulge. During expiration, the diaphragm relaxes and the abdominal muscles contract, causing the abdomen to flatten out.

- In Depth: Deep muscles. The abdominal muscles provide postural support, protect internal organs, and perform other important functions. The lower abdominal muscles help protect the pelvic cavity. The rectus abdominis is the large muscle in the middle portion of the abdomen.It facilitates the tilt of the pelvis and the curvature of the lower spine. Next to it on both sides of the body is the internal oblique.he deep muscles of the abdominal and pelvic region protect internal organs and perform the many complex movements of the spine, thighs, and hips.

Diaphragm When air is drawn into the lungs, the muscles in the diaphragm contract, and pull the central tendon inferiorly into the abdominal cavity. This enlarges the thorax and allows air to inflate the lungs. The peripheral muscle can be further divided by its origins into the sternal, costal, and lumbar regions.

Anatomy and physiology of muscles involved in breathing The rib cage also contains muscles with an expiratory action. These are the internal intercostal muscles, which slope backward; contraction causes the ribs to move downward and inward, similar to the lowering of a bucket handle. Both internal and external intercostal muscles are also involved in flexing and twisting the trunk. Read more about Breathe Strong, Perform Better.
