Anatomy Chapter 1-10 Flashcards
Name the anatomical planes?
Coronal
Sagittal
transverse
what is a fissure?
Narrow cleft like opening between adjacent parts of the bone for the passage of vessels or nerves.
what is a foramen?
opening through which blodvessels and nerves pass
what is a Fossa?
Depression (hollow) in or on a bone
what is a Sulcus (groove)
Long narrow depression that accommodates blood vessels, nerves and tendons.
What is a meatus (canal)
Tube-like passageway within a bone.
what is a sinus?
Air-filled passageway within a bone.
what is a notch?
Indentation at the edge of a bone.
what is a condyle process?
Large rounded articular prominence.
what is a facet?
Smooth flat surface.
What is a head process?
Rounded articular projection supported upon a constricted portion (neck) of the bone.
what is a crest?
prominent ridge or border
what is a epicondyle?
Prominence above a condyle
What is a linea (line)?
Less prominent ridge then a crest?
what is a Process?
Sharp slender projection
what is a Trochanter?
Very large projection found only on the femur.
what is a Tubercle?
Small rounded process
what is a Tuberosity?
Large rounded often roughened process.
Which two types of bones do we have in the body?
Compact (dense) bone tissue
Spongy (Cancellous) bone tissue
what are the characteristics of compact (dense) bone tissue
- Contains fewer and smaller spaces and more solid matter.
- it forms the external (outer) layer of all bones and the diaphyses of long bones.
Function: protect, support, weight-bearing.
what are the characteristics of Spongy (Cancellous) bone tissue
- Contains more and larger space.
- its less solid.
- usually forms the central mass of short, flat and irregular bones and the epiphyses of long bones.
- Its composed by thin plates of bone called trabeculae, the spaces between the trabeculae contain red bone marrow.
Functions of the skeletal system:
Framework
protect internal organs like heart and lungs
attachment for skeletal muscle.
storage for minerals such as calcium and phosphorus, plus yellow bone marrow which stores lipids (fat, energi storage)
containment of redbone marrow where red-blodcells, white-blodcells and platlets (hematopoiesis) are made.
