Proximal
closer to the origin of the body part or the point of attachment of a limb to the body trunk
Distal

Superficial (external)
toward or at the body surface
Deep (internal)

The standard reference point that is used when the body is i a standard position called..
Anatomical Position
explain where one body structure is in relation to another body structure
directional terms
define specific areas of the body
Regional Terms
What body parts consist of the axial major body part subdivision
head, neck, and trunk
What body parts consist of the appendicular major body part subdivision
the limbs
sagittal
A vertical plane dividing the body into left and right halves
Frontal Plane
a vertical plane dividing the body into anterior and posterior parts
Transverse
a horizontal plane dividing the body into superior and inferior parts
what does the Dorsal Cavity contain
the brain and spinal cord
The ventral cavity
Contains the viceral body organs
are enclosed in the movable joints of the body
Synovial cavities
What cavities are contained in the cranial cavity
Middle and internal ear cavities
the nasal cavity
the orbits
several air filled cavities called sinuses
How many parts compose the axial skeleton
The Skull, The Vertebral Column, and The bony Thorax
What does the vertebral column consist of
24 individual vertebrae and two fused bones called the sacrum and coccyx
How many cervical vertebrae are there?
7
How may thoracic vertebrae are there?
12
How many lumbar vertebrae are there?
5
How many fused sacral vertebrae are there?
5
how many fused coccyx are there?
4
What does the bony thorax consist of?
The sternum, 12 pairs of ribs (7 pairs of true ribs & 5 pairs of false ribs
bony thorax + the costal cartilages =
The Thoracic Cage
How many bones is the appendicular skeleton comprised of?
126 bones in the appendages and limbs, 2 bones in the pectoral girdle, 2 of the bones in the pelvic girdle
the pectoral girdle attaches the what to the axial skeleton
upper limbs
2 coxal bones + the sacrum + the coccyx =?
The pelvic girdle
the coxal bone attach what to the axial skeleton?
lower limbs
what are bumps, holes, and ridges that bones have
Bone markings
What are the two categories of bone markings?
- Projections (processes)
- Depressions (cavities, indentations, or openings )
Serve as sites of muscle or ligament attachment or help form joints
- processes
Projections
conduits for nerve and blood vessels.
- cavities, indentations, or openings
Depressions
large rounded projection; may be roughened
ex. tibial _______
Tuberosity
Narrow ridge of bone; usually prominent
ex. iliac _____
Crest
Very large, blunt, irregularly shaped process ( the only examples are on the femur)
ex. greater … and lesser …
Trochanter
Narrow ridge of bone; less prominent than a crest
ex. Interochanteric _____
line
Small rounded projection or process on a bone
ex. adductor ______
Tubercle
Raised area on or above condyle
ex. Medial ______
Epicondyle
Sharp, slender, often pointed projection
ex. Spinous Process
Spine
