  • The oldest anatomical drawing-- Egyptian
    papyrus written 16 centuries ago
  • Shows that the heart, vessels, liver, spleen,
    kidneys and bladder were recognized, and that the
    blood-vessels were known to come from the heart.

7
Aristotle (384 - 322 B.C.), 1st noted to study
animal carcasses to compare them to human bodies
8
300 B.C Herophilus Erasistratus performed
first human dissection
9
1752Englands Murder Act passed
the medical dissection of all executed murderers.

10
1832Anatomy Act allowed use of unclaimed bodies
for dissection, particularly those who died in
prison or the workhouse
11
Since King Henry V111 (1509)
  • Murderers, prisoners, prostitutes, people unable
    to pay for their burials, those that committed
    suicide were approved for human anatomy studies

12
17-19th centuryBody snatching!!!
  • Not enough corpses for medical students so many
    times freshly dug graves were excavated for
    medical research.
  • Illegal, a misdemeanor, fine and jail time if
    caught.

13
Dissection is the process of disassembling
something to determine its internal structure
as an aid to determining the function
relationships of its components.
14
Vivisection refers to the dissection of living
animals
15
Dissection is often performed as a part of
determining a cause of death in autopsy (on
humans) and necropsy (on animals) and is an
intrinsic part of forensic medicine, such as
would be practiced by a coroner.
16
Systems
17
Skeletal System
  • Its purpose is to protect organs, give shape

18
Axial Skeleton
  • Vertebra, ribs, sternum, skull
  • 80 bones in the head and trunk of the human body
  • The purpose of the axial skeleton is to protect
    the body's most vital organs.

20
Pectoral Skeleton
  • Front limbs, scapula, humerus, radius, ulna,
    phalanges, metacarpals, carpals

21
scapula
22
iguana - pectoral
23
Pelvic Skeleton
  • Rear legs, tibia, fibula, femur, tarsals,
    metatarsals, phalanges, hocks,

24
Muscles
  • Body tissue which contracts to produce movement
    or force.
  • primarily functions as a source of power
  • 3 main types of muscle
  • Smooth
  • Cardiac
  • Skeletal

25
Circulatory System
  • Heart, veins, arteries, capillaries (small blood
    vessels),lymph glands (which contain large
    numbers of white blood cells
  • Moves blood through the vessels of the body via
    the pumping action of the heart
  • Supplies tissues with nourishment
  • Collects waste from tissues

27
Anatomical Planes of the Body
  • Medical professionals often refer to sections of
    the body in terms of anatomical planes (flat
    surfaces).
  • These planes are imaginary lines vertical or
    horizontal drawn through an upright body. The
    terms are used to describe a specific body part
    (area).

28
Anatomical Planes of the Body
29
Cranial, Rostal
  • Closer to the head

30
Ventral
  • Referring to the belly

31
Proximal
  • Referring to the limbs

32
Caudal
  • Referring to the lower part of the body or tail

33
Lateral
  • Referring to the side

34
Dorsal
  • Referring to the back of the body
