Axis

A

The imaginary midline around which

the body pivots

13

The axial skeleton

A

Head and trunk

Spinal cord is axis

14
Q

The appendicular skeleton

A

Lower limbs
Upper limbs
Refer to Figure 1-1: Terms of Orientation

15
Q

Frontal plane

A

Divides body into front and back halves

16
Q

Sagittal plane

A

Divides body into right and left halves

17

A

Divides body into upper and lower halves

18
Q

Anterior or ventral surface

A

Front of body

19

Posterior or dorsal surface

A

Back of body

20
Q

Superficial surface

A

Surface of body

21
Q

Deep

A

Direction away from the surface

22
Q

Deep Surface

A

Direction away from the surface

23
Q

Superior Body Position

A

Upper regions of body

24
Q

Inferior Body Position

A

Lower regions of body

25
Q

Prone Body Position

A

Body horizontal with face down

26

Lateral

A

The side

28
Q

Proximal

A

Point closest to the trunk

29
Q

32
Q

Plantar

A

Sole of the foot

33
Q

Palmar

A

Palm of the hand

34
Q

Epithelial tissue

A

Covers surfaces of the body

Covers linings of cavities and
passageways

Acts as a barrier against hostile agents such as
infectious organisms

Prevents dehydration and fluid loss

35
Q

Connective tissue

A

Binds together and supports tissues
and organs
May be solid, liquid, or gel-like

Areolar tissue: adipose and lymphoid tissue

Fibrous tissue: binds structures together

Cartilage: hyaline, fibro-cartilage, yellow
(elastic) cartilage

Blood: plasma and blood cells

Bone: hardest form of connective tissue

36
Q

Muscular tissue

A

Muscular tissue is contractile

Classifications of muscular tissue
Voluntary striated muscle (skeletal muscle)
Involuntary smooth muscle
Cardiac muscle

Refer to Figure 1-2: Striated and smooth muscle and
Table 1-1: Tissue Types

37
Q

Nervous tissue

A
Specialized for communication
Consists of neurons or nerve cells  
Functions to transfer information 
From one neuron to another
From neuron to muscle
From sensory receptors to other neural entities
38
Q

Nervous tissue

A

Specialized for communication

Consists of neurons or nerve cells

Functions to transfer information:
From one neuron to another
From neuron to muscle
From sensory receptors to other neural entities

39
Q

Organs

A

body tissues combined together to
perform a special function

Organ tissues all serve the same
general purpose

40
Q

Fascia

A

Membrane that surrounds organs

41
Q

Ligaments

A

Fibrous tissue that connects bones or cartilage

42
Q

Tendons

A

Connective tissue that attaches muscle to bone

or cartilage

43
Q

Muscles

A

Aggregates of contractive muscle fibers
with a common function

Can shorten to about half their length

Origin is the point of attachment of the least
mobile element
Insertion is the point of attachment that
moves when a muscle contracts

Refer to Figure 1-7: Mechanical advantage
derived from point of insertion

44
Q

Agonists

A

Muscles that move structures

45
Q

Antagonists

A

Muscles that oppose contraction of agonists

46
Q

Synergists

A

Muscles that stabilize structures

47
Q

Muscle Innervation

A

Muscles are innervated by a single
nerve

Innervation can be sensory (afferent)
or excitory (efferent)

A motor unit consists of:
One efferent nerve fiber
Muscle fibers it innervates

48
Q

Body Systems

A

Systems are groups of organs that
perform a specific function

Failure or deficiency of an organ causes
functional disorders

Organs can be part of more than one
system
