  • Adduction: Movement of any part returning to the midline in the coronal plane.
  • Rotation: Turning or twisting of a body part around its long axis.
    • Lateral rotation: Body part rotates away from the midline.
    • Medial rotation: Body part rotates toward the midline.
  • Circumduction: Combination of flexion/extension, abduction/adduction, and rotation.
  • Pronation: Radius rotates over ulna, palm faces backward.
  • Supination: Radius and ulna are parallel, palm faces forward.
  • Opposition: Movement between thumb and medial four fingers (thumb touches the tips of the other fingers).

Deep Fascia

  • Modifications of deep fascia:
    • Forms capsules, synovial membranes, and bursae in relation to joints.
    • Forms aponeuroses in palms and soles, which afford protection to underlying structures.
    • Forms retinacula near some joints to hold tendons in place.
    • Forms interosseous membrane in the forearm and leg.

Skeletal System

  • Includes bones and cartilages.
  • The supporting framework of the body.
  • Primarily designed for more effective production of movements by attached muscles.

Divisions

  • Axial Skeleton:
    • Skull: 8 cranium bones, 14 face bones, 1 hyoid bone, 6 auditory ossicles (3 per ear).
    • Vertebral column: 26 bones.
    • Thorax: 1 sternum, 24 ribs.
    • Total: 80 bones.
  • Appendicular Skeleton:
    • Pectoral (shoulder) girdles: 2 clavicles, 2 scapulas.
    • Upper extremities: 2 humeri, 2 ulnas, 2 radii, 16 carpals, 10 metacarpals, 28 phalanges.
    • Pelvic girdle: 2 pelvic/hip bones.
    • Lower extremities: 2 femurs, 2 fibulas, 2 tibias, 2 patellas, 14 tarsals, 10 metatarsals, 28 phalanges.
    • Total: 126 bones.

Joints

  • Structural Classifications: Fibrous, Cartilaginous, Synovial.
  • Functional Classifications: Synarthrosis (immovable), Amphiarthrosis (slightly movable), Diarthrosis (freely movable).
  • Fibrous joints:
    • Sutures: Joined by fibrous connective tissue, found between the bones of the skull.
    • Syndesmoses: Joined by ligaments or interosseous membranes, e.g. between the tibia and fibula.
    • Gomphosis: Peg-and-socket joint, e.g. between a tooth and its socket.
  • Cartilaginous joints:
    • Primary (Synchondrosis): Joined by hyaline cartilage, e.g.costal cartilage.
    • Secondary (Symphysis): Joined by fibrocartilage, e.g. intervertebral discs.
  • Synovial joints: Freely movable joints, characterized by a synovial membrane and articular cartilage.

Synovial Joint Types

  • Plane joints: Allow gliding/sliding movements, e.g. carpal bones.
  • Hinge joints: Uniaxial movement, like a door hinge, e.g. elbow.
  • Pivot joints: Uniaxial movement (rotation), e.g. between radius and ulna.
  • Condylar joints: Biaxial movement, e.g. knee joint.
  • Saddle joints: Biaxial movement, e.g. thumb joint.
  • Ellipsoid joints: Biaxial movement, e.g. wrist joint.
  • Ball-and-socket joints: Multiaxial movement, e.g. shoulder joint and hip joint.

Muscular System

  • Types: Skeletal muscle, Cardiac muscle, Smooth muscle

Nervous System

  • The nervous system controls and coordinates the body's functions

First Week of Development

  • The first week of development begins with fertilization and ends with the formation of the blastocyst.

Blastocyst Formation

  • The morula enters the uterine cavity on day 4 after fertilization.
  • A fluid-filled space called the blastocoel appears inside the morula.
  • The conceptus is now called a blastocyst.
  • The inner cell mass is renamed the embryoblast.
  • The outer cell mass is renamed the trophoblast.

Embryoblast and Trophoblast

  • The embryoblast gives rise to the embryo proper.
  • The trophoblast contributes to the placenta later in development.

Second Week of Development

  • Highlights:
    • Implantation completes.
    • Trophoblast differentiates into cytotrophoblast and syncytiotrophoblast .
    • Inner cell mass (embryoblast) differentiates into epiblast and hypoblast.
    • Formation of amniotic cavity, yolk sac, and chorionic cavity.
    • Development of extraembryonic mesoderm.
    • Extraembryonic mesoderm splits into somatic and splanchnic mesoderm.
    • Beginning of primitive utero-placental circulation.

Third and Fourth Week of Development

  • Highlights:
    • Appearance of the primitive streak.
    • Gastrulation: Formation of germ layers.
    • Development of the notochord
    • Neurulation: Formation of the neural tube.
    • Differentiation of the three germ layers.

Germ Layer Differentiation

  • Invagination of cells displaces the hypoblast and forms the embryonic endoderm.
  • Cells between the epiblast and the endoderm form the intraembryonic or embryonic mesoderm.
  • The remaining cells of the epiblast form the embryonic ectoderm.

Ectoderm

  • Neuroectoderm: Forms the nervous system (brain, spinal cord).
  • Surface ectoderm: Forms the epidermis, hair, nails, sweat glands, and mammary glands.

Embryonic Mesoderm

  • Paraxial mesoderm: Forms somites on either side of the neural tube; gives rise to skeletal muscle, cartilage, and connective tissues.
  • Intermediate mesoderm: Lies lateral to paraxial mesoderm; gives rise to the urogenital system.
  • Lateral plate mesoderm: Continues with extraembryonic mesoderm; gives rise to body wall, wall of the digestive tract, and limbs.

Folding

  • Cephalocaudal folding: The head and tail ends of the embryo bend inwards, causing the embryo to fold from head to tail.
  • Lateral folding: The sides of the embryo fold inwards, bringing the lateral body walls together to meet at the midline.
