Myology - Coggle Diagram
Myology
characteristics of muscles that are used as references in naming muscles
Location: Using the name of a nearby bone or a position (lateral, medial, internal, or external)
Size: Using terms such as maximus, major, minor, longus, or brevis
Shape: Circular (orbicularis), triangular (deltoid), or trapezoid (trapezius)
Direction of Fibers: Straight (rectus) or angled (oblique)
Number of heads (attachment points): Indicated by the suffix “-ceps”, as in biceps, triceps, and quadriceps
Action: Flexor, extensor, adductor, abductor, or levator
boundaries of the OCF area
Scalp
Anterior: From the forehead to supraorbital margin (above the eyes)
Posterior: Superior nuchal line of the occipital bone
Lateral: Temporal lines / zygomatic arches
Layers: Skin, Conective tissue, Aponeurosis, Loose connective tissue, Pericranium
Facial
Superior : Hairline of the scalp
Inferior: The lower border of mandible and chin
Lateral: Location between the ears
Nerves: Trigerminal Nerve (CN V), Motor branches of the facial nerve (CN VII)
OCF Bones
Cranial Bones: Frontal, Parietal, Occipital, Temporal, Sphenoid, Ethmoid
Facial Bones: Maxilla, Zygomatic, Mandible, Nasal, Lacrimal, Vomer, Palatine
definition and function of skeletal muscles
Skeletal muscles is a separate organ composed of hundreds to thousands of cells, which are called muscle fibers
Function
Producing motions: Movements of the body is a result of muscular contractions (skeletal muscles, bones, and joints)
Stabilizing body positions: Skeletal muscle contractions stabilize joints and help maintain body positions
Storing and moving substances within the body: Skeletal muscle contractions promote the flow of lymph and returns the blood in veins to the heart.
Generating heat: The contraction produces heat (thermogenesis). Used to maintain normal body temperature.
