Q

A

The hyoid bone and auditory ossicles in the middle ear are functionally

Q

define the following skull bones:

cranium.

28
Q

define the following skull bones:
sphenoid

A

Butterfly shaped bone in mid-part of base of skull; articulates with
all other cranial bones; forms part of the orbits.

29
Q

define the following skull bones:
ethmoid

A

Located in anterior cranial floor, medial to orbits; sponge-like in
appearance.

30
Q

define the following facial bones:
maxilla

A

Unite to form the upper jaw; articulates with every facial bone
except mandible.

31
Q

define the following facial bones:
zygomatic

A

Cheekbones; articulates with the frontal, maxilla, sphenoid &
temporal bones.

32
Q

define the following facial bones:
mandible

A

Lower jawbone; the only movable skull bone
(other than auditory ossicles).

33
Q

Look at the newborn human and chimpanzee skulls. What do you notice about
the forehead region that is different from adult skulls?

A

There are 2 separate frontal bones in the newborn skull

34
Q

Look at the small primate resource provided, which exhibits the forehead feature
you identified above in the newborn human and chimpanzee skulls.
What might this suggest about the evolutionary relationship of the three animals?

A

They share a common ancestor.

35
Q

Compared to the other specimens, what do you notice about the mandible of the
human and chimpanzee newborn specimens and the small adult primate skull?

A

The mandibles consist of 2 separate bones that are unfused.

36
Q

What might the comparative anatomy of the jaws of these three animals suggest
about their evolutionary relationship?

A

They share a common ancestor

37
Q

Compared to the adult chimpanzee and small primate, what do you notice about
the positional relationship of the adult human face relative to the skull? What
might account for this difference?

A

The chimpanzee and small primate’s faces sit in front of the skull but the human
face is positioned under the skull. This is due in part to the large human brain.

38
Q

The large hole at the base of all skulls is called the foramen magnum (which
basically means big hole!). What do you think passes through this hole?
What bony structure is this feature passing into next?

A

Spinal cord. Vertebral column

39
Q

Define the following vertebral regions and where the axial region is
cervical (7)

A

Neck region; smaller than all other vertebrae except coccygeal vertebrae. Has transverse foramen (holes) to allow the passage of blood vessels.

40
Q

Define the following vertebral regions and where the axial region is
thoracic (12)

A

Chest region; larger than cervical vertebrae; articulate with ribs.

41
Q

Define the following vertebral regions and where the axial region is
lumbar (5)

A

Lower back; largest of the unfused
vertebrae.

42
Q

Define the following vertebral regions and where the axial region is
sacrum (5)

A

Triangular bone formed by fusion of sacral vertebrae.

43
Q

Define the following vertebral regions and where the axial region is
coccyx (4)

A

Triangular; formed by fusion of coccygeal
vertebrae; articulates with apex of sacrum.

44
Q

Unlike all other primates, the apes (humans, gorillas, chimpanzees, orangutans and gibbons), do not have a tail. Instead, apes have a coccyx, which is considered a remnant of the tail. What does the presence of a vestigial tail suggest about the evolutionary relationship of the apes and other primates?

A

They share a common ancestor.

45
Q

List 4 functions you think the vertebral column performs.

A
  1. Support of the head and trunk (weight bearing)
  2. Protection of the spinal cord
  3. Attachment site for muscles (movement)
  4. Attachment site for ribs / attachment sit for pelvis
46
Q

List the bony evidence you would use to support for your conclusions about the
functions of the vertebral column.

A

multiple vertebra

47
Q

read this appendicular skeleton

A

The appendicular skeleton consists of the bones of the upper and lower limbs and the bones that form the girdles that connect the limbs to the axial skeleton. The primary function of the appendicular skeleton is movement.

48
Q

read this pectoral shoulder

A

The pectoral (shoulder) girdles attach the bones of the upper limbs to the axial skeleton. The pectoral girdles do not articulate with the vertebral column; they are held in place by muscles that extend from the vertebral column and ribs to the scapula.

49
Q

read this pelvis

A

The pelvic (hip) girdle attaches the bones of the lower limbs to the axial skeleton and consists of two coxal bones (also called os coxa, pelvic bones, hip bones) articulating with the sacrum. Each coxal bone is formed by the fusion (in the adult) of the three bones: the ilium, ischium and pubis.
