Superior oblique muscle

three lobes separated by two fissures and the left lung has two lobes separated by one fissure and a depression called the cardiac notch. Both lungs have an oblique fissure which extends inferiorly and anteriorly. It divides the left lung into superior and inferior lobes. The oblique and horizontal fissures divide the right lung into superior, middle, and inferior lobes. Each lobe receives its own secondary (lobar) bronchus. The right primary bronchus gives rise to

The air flow will control how quickly the diaphragm goes up. The rebounding (equilibrium) forces also activated when lung-thorax unit is compressed. Their needs to be a maintained airflow and subglottal pressure. Use inspiratory muscles to control air flow coming out at first. Still contracts the diaphragm and controls how quickly it goes up. Still contracts the external intercostals and others to control rib cage. Going down slower and volume decreases much slower. Positive pressure

name of a muscle can distinguish its location, action, shape, and function. Select five different muscles to make this distinction. Descriptive terms are used to name skeletal muscles. Some names give the location in the body. The temporalis muscle is attached to the temporal bone in the skull. The brachialis muscle is attached to the humerus bone, but brachial refers to the main artery in the arm. Some muscles are named for their origins and insertions, like the genioglossus muscle, for example

3. While performing the off-centre attitude in parallel different groups of muscles contract to produce movement needed to execute this balance. Beginning from the lower half of the body there are primary muscles that contract to produce dorsiflexion of the calcaneus: the tibialis anterior and pernoneous tertius are the agonists and the peroneous longus and peroneous brevis are the antagonists of this action. Although, when dorsiflexion reverses to plantaflexion the roles of agonist and antagonist

the corrugator cutis ani, thereby forming an intra-sphincteric fibro-elastic network passing through the external sphincter(Stoker, 2009). External anal sphincter The external sphincter is a cylindrical striated muscle under voluntary control and comprises predominantly slow-twitch muscle fibres, capable of prolonged contraction. With age there is a shift towards more type II (rapid) fibres (Cni, 1993). The external sphincter has a nerve supply by the inferior rectal branch of the pudendal nerve (S2

One of the unique abilities that set humans apart from other life forms is the ability of speech production. Although it occurs involuntarily the act of speaking can be traced back to neural level even before the muscles are directed to move or before the first breathe is taken to supply the energy source for speech. Most people may not realize it but the fact is saying a word or even a sound is quite laboring on the body, especially when it must occur rapidly to even create a single sentence. Before

pictures by using special kinds of radiographic imaging like fluoroscopy, MRI, CT and contrast. Contrast material is a dye that is injected into the patient and helps the doctor see the soft tissue structures of that joint such as tendons, ligaments, muscles, cartilage and joint capsule (Healthwise Staff, 2014, p. 1).Contrast is either injected directly into the joint or indirectly where the dye is injected into the bloodstream and absorbs into the joint. Without contrast these structures would not be

that describes which nerves control which muscles to cause the needed eye movements). Action: Muscle: Origin: Insertion: Nerve: Eye looks down Inferior Rectus Sphenoid around optic canal Inferior, medial surface of eyeball Oculomotor Nerve III Eye looks laterally Lateral Rectus Sphenoid around optic canal Lateral surface of eyeball Abducens Nerve VI Eye rolls, looks down and laterally Superior Oblique Sphenoid around optic canal Superior, lateral surface of eyeball Trochlear

female reproductive system are all located in the lower third of the abdomen. The Male reproductive system: The penis and the urethra are part of the urinary and reproductive system. Musculoskeletal system (MS)-Musculoskeletal system is made up of muscles, skeletal, cartilage, tendons, ligaments joints and other tissues connected that support and binds tissues and organs together. Immune system (IS) - The immune system consists of three major parts; B-cells which are produced in bone narrow, T-cells

speech. The Lower Respiratory Tract includes the trachea which is the airway to the lungs, the lungs which provide oxygen and exhales carbon dioxide, the bronchi which create passages that supply the air and the diaphragm which is the main respiratory muscle. The function of the Digestive System is digestion and absorption. The food is broke down and digested then absorbed by the body. The Digestive System is separated into two main parts. The digestive tract, or alimentary canal, is a continuous tube
