Document Summary
The notochord is now the nucleus pulposus of the intervertebral disks. Pharyngeal slits now are associated with structure of the head: vertebrate characteristics, vertebrae (we are vertebrates bc we have a vertebra. Part that goes dorsal is out of the spinous processes, last part of the cervical section is the vertebral processes (c7) Evolution and development: vertebrates are segmental animals, they exhibit serial repetition of structures along the longitudinal axis of the body. Development: serial homology (structures that aris from the same origin)/ segmentation (division of the body into specific units, embryonic somites, bilaterally paired blocks of mesoderm tissue, somites become vertebrae, ribs, skin, and some muscles. Actions occur around a joint and are caused by mm. Anatomical position: spine erect, palms and feet forward. Skeletal systems: axial: skull, vertebral column, ribs, appendicular limbs and girdles (shoulder and pelvis (s1-5)) everything that hangs on/off of axial skeleton. Joints (3 types) don"t move easily: 1.
