Ch. 10 Musculoskeletal System Flashcards
The musculoskeletal system includes:
muscles, bones, joints, and related structures (tendons and connective tissue that function in the support and movement of body parts and organs)
articulation
Place of union between two or more bones; also called joint
hematopoiesis
Production and development of blood cells, normally in the bone marrow
ligaments
Connective tissue that surrounds the joint capsule to bind bones to other bones
tendons
Connective tissue that binds muscle to bone on either side of a joint
Muscle tissue is composed of:
contractile cells, or fibers, that provide movement of an organ or body part.
Muscles contribute to:
posture, produce body heat, and act as a protective covering for internal organs.
three types of muscle tissue in the body:
- Skeletal
- Smooth
- Cardiac
Skeletal muscles
attached to bones
provide means for movement
voluntary muscles
aka striated muscles
voluntary muscles
contract and relax in response to conscious thought
Smooth muscles
assist internal process (digestion, circulation, urination)
called visceral muscles
aka involuntary muscles
involuntary muscles
movement is not under conscious control but functions under the control of the autonomic (involuntary) nervous system
Cardiac muscle
in heart wall
forms the myocardium
striated like skeletal muscle
produces rhythmic involuntary contractions like smooth muscle.
Adduction
Moves closer to the midline
Abduction
Moves away from the midline
Flexion
Decreases the angle of a joint
Extension
Increases the angle of a joint
Rotation
Moves a bone around its own axis
Pronation
Turns the palm downward
Supination
Turns the palm upward
Inversion
Moves the sole of the foot inward
Eversion
Moves the sole of the foot outward
Dorsiflexion
Elevates the foot
Plantar flexion
Lowers the foot (points the toes)
Bones functions:
the framework of the body, protect internal organs, allow for movement, store calcium and other minerals, and produce blood cells within bone marrow (hematopoiesis)
Movement is possible because bones provide
points of attachment for muscles, tendons, and ligaments
Bones store:
calcium
phosphorus
four principal types of bone:
short
irregular
flat
long
Short bones
somewhat cube-shaped (nearly equal LxW)
e.g. bones of the wrist (carpals) and ankles (tarsals)
Irregular bones
not “short” or “long” because of complex shapes
e.g. vertebrae and bones of middle ear
Flat bones
provide broad surfaces for muscular attachment or protection of internal organs
e.g. skull, shoulder blades, and sternum.
Long bones
in extremities (legs, arms, and fingers) regular, well-defined shapes each long bone has three main parts
3 main parts of long bones:
diaphysis
epiphyses
periosteum
diaphysis
the shaft, or long, main portion of bone
compact bone that forms cylinder
surrounds medullary cavity (central canal filled with “yellow bone marrow,” composed of blood vessels and fatty tissue)
epiphyses
ends of bone (distal/ proximal epiphyses)
somewhat bulbous shape provides space for muscle and ligament attachments near the joints
consists of 3 tissue layers
3 tissue layers of epiphyses
articular cartilage
compact bone
cancellous bone
articular cartilage
- thin outer layer of cartilage where bones meet/form joints
- epiphyseal line (growth plate), area of cartilage constantly replaced by new bone tissue as the bone grows, lengthens bones during childhood/adolescence, calcifies/disappears at full growth
compact bone
thick, dense layer of hard compact bone
cancellous bone
aka spongy bone
inner layer
porous tissue less dense than compact bone
filled with red bone marrow
periosteum
dense, white, fibrous membrane, covers bone surfaces
contains blood/lymph vessels, nerves, osteoblasts
provides bone repair, general bone nutrition, and attachment point for muscles, ligaments, and tendons.
Surfaces of bones are rarely smooth but consist:
projections articulating surfaces depressions openings (muscle and ligament attachment, pathways/openings for blood vessels/nerves)
How many bones does an adult skeleton have?
206
How is the skeleton divided?
axial and appendicular
3 major regions of axial skeleton and their function:
skull, rib cage, vertebral column
contributes to formation of body cavities and provides protection for internal organs, such as the brain, spinal cord, and organs enclosed in the thorax.
2 types of skull bones:
cranial and facial
Most skull bones are joined by:
sutures
Sutures:
lines of junction between two bones, especially of the skull, and are usually immovable
cranium
aka skull
made up of 8 bones
enclose and protect the brain and the organs of hearing and equilibrium
___________ are connected to muscles to provide head movements, chewing motions, and facial expressions.
cranial bones
8 cranial bones:
frontal parietal (2) occipital temporal (2) sphenoid ethmoid
fontanels
aka soft spots
fibrous membranes, connect cranial bones at birth
enables infant’s skull movement during birth
close as cranial bones grow together.
frontal bone
forms the anterior portion of the skull (forehead) and the roof of the bony cavities that contain the eyeballs.
parietal bone
one on each side of the skull just behind the frontal bone. Together they form the upper sides and roof of the cranium. Each parietal bone meets the frontal bone along the (3) coronal suture.
occipital bone
forms the back and base of the skull. It contains an opening in its base through which the spinal cord passes.
temporal bone(s)
Two (5) temporal bone(s), one on each side of the skull, form part of the lower cranium. Each temporal bone has a complicated shape that contains various cavities and recesses associated with the internal ear, the essential part of the organ of hearing and balance.
mastoid process
downward projections of the temporal bones
provides a point of attachment for several neck muscles.
sphenoid bone
located at the middle part of the base of the skull, forms a central wedge that joins with all other cranial bones, holding them together.
ethmoid bone
is the anterior cranial bone located between the nasal cavity and parts of the orbits of the eyes.
All facial bones, with the exception of the _______, are joined together by sutures and are immovable
mandible (lower jaw bone)
Movement of the mandible is necessary for
speaking and chewing (mastication)
maxillae
paired upper jawbones, are fused in the midline by a suture. They form the upper jaw and hard palate (roof of the mouth). If the maxillary bones do not fuse properly before birth, a congenital defect called cleft palate results.
2 facial bones that contain sockets for teeth:
maxillae and mandible
nasal bones
Two thin, nearly rectangular bones lie side by side and are fused medially, forming the shape and the bridge of the nose.
lacrimal bones
Two bones located at the corner of each eye. These thin, small bones unite to form the groove for the lacrimal sac and canals through which the tear ducts pass into the nasal cavity.
zygomatic bones
2 bones
(cheekbones)
located on the side of the face below the eyes and form the higher portion of the cheeks below and to the sides of the eyes.
vomer
is a single, thin bone that forms the lower part of the nasal septum.
paranasal sinuses
frontal
ethmoidal
sphenoidal
maxillary sinuses
(cavities in cranial/facial bones they are named after)

bones of the upper and lower limbs and their girdles, which attach the limbs to the axial skeleton.
appendicular skeleton function:
enables body movement
pectoral girdle consists of:
clavicle (collarbone)
scapula (triangular shoulder blade)
The primary function of the pectoral girdle is:
to attach the bones of the upper limbs to the axial skeleton and provide attachments for muscles that aid upper limb movements.
The paired pectoral structures and their associated muscles form the:
shoulders of the body.
The skeletal framework of each upper limb includes:
the arm, forearm, and hand.
Anatomically speaking, the arm is:
only that part of the upper limb between the shoulder and elbow.
Each upper limb consists of:

Differences in male/female pelves:
size/shape
males - bones larger/heavier and possess larger surface markings
female - shallower/wider
pelves are divided into:

3 pelvis bones fuse together (adult) to form:
a single hip bone called the innominate bone
acetabulum
deep socket of hip joint, inferior portion of illium
joins the pubis

between the bladder and the rectum.
lower limbs support:
complete weight of erect body (more force during running/jumping thus bigger than upper limb bones)
three parts of each lower limb:
the thigh, the leg, and the foot.
The thigh consists of:
a single bone called the femur. It is the largest, longest, and strongest bone in the body.
The leg is formed by two parallel bones:
tibia and fibula
A small triangular bone located anterior to the knee joint
