Overview: This is an audio lecture presentation on the muscles of the body. Body muscles lecture is a presentation of slides and audio which give a systemic lecture of the muscles of the body. There are 29 slides and the presentation lasts about 44 minutes. The muscles covered include the muscles of the chest, shoulder, arm, forearm, hand, thigh, gluteal region, leg, foot, facial expression, mastication, tongue, pharynx, larynx, neck, thorax, back, abdomen, thoracic diaphragm, pelvic diaphragm, urogenital diaphragm. In some instances, specific nerves are identified. The presentation would be appropriate for advanced high school students or college general education students.
Learning Goals: After completing this presentation, the learner would be able to:
  • Identify major muscles of the body
  • Describe actions of the major muscles of the body
Target Student Population: The target population includes advanced high school students or college general education students.
Prerequisite Knowledge or Skills: There are no pre-requisites for this learning material.
Type of Material: This material is provided in lecture / presentation format.
Recommended Uses: The presentation could be given in class or assigned as a preview before starting the muscle section.
Technical Requirements: Technical requirements include Adobe Flash Play along with a web browser.

Evaluation and Observation

Content Quality

Rating: 4 stars
Strengths:
  • Covers a lot of material in a moderate time span
  • Concise and relevant
  • Very clear presentation
  • Content cover core curriculum within the discipline
  • Covers foundational material for muscle anatomy
  • Includes an adequate amount of material
  • Provides useful and accurate information
Concerns:
  • An outline or list of the regions the slides cover would be helpful to rapidly find specific slide(s)
  • The audio is specific for requirements the presenter had for her class; for example, knowing some attachments or not needing to know those attachments
  • Some incorrect information given for example: 1)slide 7 the flexor digitorum superficialis attaches to the middle phalanx, 2)slide 14, “extensor digitorum” should be extensor digitorum longus,” 3)slide 16, both “flexor hallucis” and “flexor digitorum” should be “flexor hallucis longus” and “flexor digitorum longus,” 4)slide 18, the platysma does not extend the head when a man ties a tie, 5)slide 21, the constrictors are voluntary muscles, not involuntary, and 6)slide 28 the pelvic diaphragm includes both the levator ani and coccygeus
  • Content is not up to date; the urogenital diaphragm is no longer used; recent research now defines the area as the urogenital triangle made up of a superficial perineal pouch and a deep perineal pouch.
  • On slide 14, the arrow pointing to extensor hallucis longus look like it’s pointing to extensor hallucis brevis
