Pre-lab 4: Skeletal and Muscle Basics Skeletal Basics  List the major anatomical categories of bones, provide an example of each  Draw a long bone, label the following structures: epiphyses, diaphysis, articular cartilage, locations of spongy and compact bone.  Draw an osteon, label the following structures: central canal, lacunae, canaliculi  Define the listed bone surface markings, your lecture textbook is great resource for finding this  information (Page 180 – Table 6.2).  Protrusions  Depressions or holes o Condyle o Facet o Epicondyle o Meatus o Line o Alveolus o Crest o Sinus o Head o Foramen o Process o Fossa o Spine o Trochanter o Tubercle o Tuberosity Muscle Basics  Practice the listed of some muscle nomenclature terms, you will need to know these as we begin identifying muscles of the appendicular and axial regions of the human body. There will be more over the next two lab sessions.  Location  Shape o Abdominis – abdomen o Deltoid – triangular o Brachium – arm o Trapezius – trapezoid o Femoris – thigh o Piriformis – pear shaped o Gluteus –buttock o Pectoralis – chest  Direction of muscle fibers o Rectus – straight or parallel o Transverse – at right angles or perpendicular  Size o Oblique – slanted (neither perpendicular no parallel o Brevis – short o Longus – long o Maximus – largest  Origin points o Minimus – smallest o Bi – two o Tri – three o Quad – four o …ceps – head of muscle
