What are Hypobranchial muscles?
The hypobranchial muscles of jawed fishes are straplike muscles running from the pectoral girdle to the structures of the visceral skeleton, the jaws, and the gill bars. Some muscles, such as the coracomandibularis, are specialized as jaw openers, although most of the work of jaw opening…
What are appendicular muscles?
T he appendicular muscles control the movements of the upper. and lower limbs, and stabilize and control the movements of the pectoral and pelvic girdles. These muscles are organized into groups based on their location in the body or the part of the skeleton they move.
What are vertebrate muscles?
Major types of vertebrate muscles In terms of its microscopic structure, the musculature of vertebrates is usually divided into three types: striated, cardiac, and smooth muscle. Smooth and cardiac muscle are under the control of the involuntary, or autonomic, nervous system.
What are Branchiomeric muscles?
Branchiomeric muscles. The muscles derived from branchial arch mesoderm that provide a large portion of the musculature for the face and neck.
What is the original function of the Hypobranchial muscle?
Hypobranchial muscle is located below the pharynx, from the pectoral girdle to the jaw. It functions in respiration and feeding.
What is axial muscle?
1. axial muscle – a skeletal muscle of the trunk or head. skeletal muscle, striated muscle – a muscle that is connected at either or both ends to a bone and so move parts of the skeleton; a muscle that is characterized by transverse stripes.
Where are the appendicular muscle?
The appendicular muscles of the lower body position and stabilize the pelvic girdle, which serves as a foundation for the lower limbs. Comparatively, there is much more movement at the pectoral girdle than at the pelvic girdle.
What are axial and appendicular muscles?
Axial muscles originate on the axial skeleton (the bones in the head, neck, and core of the body), whereas appendicular muscles originate on the bones that make up the body’s limbs.
What are the three types of muscle tissue found in vertebrates?
Overview. The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.
What are the skeletal muscles?
Skeletal muscle: Skeletal muscles are voluntary muscles, meaning you control how and when they move and work. Nerves in your somatic nervous system send signals to make them function. If you reach for a book on a shelf, you’re using skeletal muscles in your neck, arm and shoulder.
Is the levator Palpebrae Superioris in extraocular muscle?
The extraocular muscles (extrinsic ocular muscles), are the seven extrinsic muscles of the human eye. Six of the extraocular muscles, the four recti muscles, and the superior and inferior oblique muscles, control movement of the eye and the other muscle, the levator palpebrae superioris, controls eyelid elevation.
Where are Epaxial muscles located?
Epaxial muscles (epi = upon & axial = axis) are muscles located dorsally along the spine. They are innervated by dorsal branches of spinal nerves and function to extend the vertebral column. Generally, epaxial musculature consists of fascicles running from one vertebra to neighboring vertebrae.
What are the different muscles in the back?
There are three different muscle groups found in the back: the superficial group, the deep group, and the intermediate group. Muscles found in the superficial group include rhomboid major, rhomboid minor, levator scapulae, trapezius, latissimus dorsi.
What are the four muscle groups that make up the deep muscle?
The deep muscle group can be subdivided into four smaller groups muscles. The four muscle groups that together make up the deep muscle group are the segmental muscles, the transversospinales, the erector spinae, and the spinotransversales.
What are the most common types of back pain?
Back pain is one of the most common kinds of pain for adults, and muscle strains are the most common type of back pain. Muscle or ligament strains can occur from repeated use of the muscles, or from improperly or awkwardly lifting heavy objects.
What organs are found in the human back?
Beyond the muscles found in the back, there are also several organs found within the human back. The kidneys and lungs are located in the back, with the lungs found within the rear portion of the rib cage and the kidneys situated near muscles just below the cage.
