  1. pectoral girdle
    superior girdle of the vertebrate body that connects and supports the arms/ forelimbs to the vertebral column

    generally consists of scapulae, clavicles, coracoids, or procoracoids, give or take some parts dependign on the organism

    ball and socket joint connecting to the arms/ forelimbs provides great range of motion and a locomotive advantage
  2. Pelvic girdle
    • inferior girdle of the vertebrate body that connects and supports the legs/ hind limbs to the vertebral column
    • generally consists of three parts: the ilium, ischium, and pubis--which may or may not be fused

    has a ball and socket joint that allows for wide range of motion for legs/ hind limbs
  3. Similarities between human and turtle pelvic/pectoral girdle

    - articulations
    Both are sturdy, symmetrical sockts for limb articulation by connecting to the vertebral column
  4. Similarities between human and turtle pelvic/pectoral girdle

    - function
    Both also serve function of protecting internal organs
  5. Similarities between human and turtle pelvic/pectoral girdle

    - Make up
    Both made up by pairs of bones
  6. Similarities between human and turtle pelvic/pectoral girdle

    - What they have
    Both have rotator joints for large range of motion
  7. Differences between pelvic and pectoral girdle
    - characteristic
    Generally, the pectoral girdle is longer with a greater range of motion due to less articulations while the pelvic girdle is lighter but can bear more weight
  8. Differences between pelvic and pectoral girdle
    - opening
    pectoral opens towards back while pelvic opens towards front
  9. Differences between pelvic and pectoral girdle
    - evolution
    pectoral has a dual evolutionary origin, as it is composed of both dermal and endochondral bones, while pelvic has single origin and consists of only endochondral bones
  10. Differences between pelvic and pectoral girdle
    - connection
    pectoral connects to vertebral column via muscles while pelvic typically connects directly
  11. Cranial musculature
    muscles of the face, neck, and cranium
  12. There are two types cranial musculature. Explain them.
    They both embryologically arose from paraxial mesoderm:

    - branchiomerc musculature

    - hypobranchial musculature
  13. Branchiomeric musculature-- General overview
    arises from cranial paraxial mesoderm (somitomeres) and three types of arches

    • - mandibular
    • - hyoid
    • - branchial
  14. Hypobranchial musculature- General overview
    arises from trunk paraxial mesoderm (somites)
  15. Branchiomeric musculature-- in further detail
    forms arches made up of constrictor (laterally extending muscle), adductor (most medial part of muscle), and dorsal and ventral branchial muscles (attached to the tips of the arches)
  16. There are three types of arches made by the branchiomeric musculature:
    1-3)?
    1) mandibular arch: located or in contact wth the mandible involved in the force to close the jaw

    2) Hyoid arch: starts as a gill arch in primitive fish, many mammalian facial muscles are derived from hyoid arch, can form the hyoid apparatus

    3) Branchial: involved in forming the structure of the throat, feeding apparatus in fish, in tetrapods; it extends to scapula to form trapezius and mastoid
  17. Hyporamusculature-- in further detail
    Hypobranchial arches arise from cervical somites

    supplied with spinal nerves

    in fish, they originate from the coracoid region and are involved in opening jaw and expanding buccal cavity

    in tetrapods, contribute muscles to form throat, hyoid apparatus, larynx, and tongue
