Introduction Flashcards
a form of cardiac pain that occurs on exertion and disappears on rest
Angina
Caused by narrowing of the coronary arteries so that the cardiac muscle has insufficient blood.
Angina
Major cause of death in industrialized nations
Myocardial infarction
2 importance in making the diagnosis and
treating this patient.
Knowledge of:
The blood supply to the heart.
The arrangement of the coronary arteries.
Is the science of the structure and function of the
body
Anatomy
Study of the macroscopic structure and function of the body as it relates to the practice of
medicine and other health sciences.
Clinical anatomy
Study of the minimal amount of
anatomy consistent with the understanding of the overall
structure and function of the body
Basic anatomy
The person is standing erect, with the upper
limbs by the sides and the face and palms of the hands
directed forward
Anatomic

This is a vertical plane passing through the center of
the body, dividing it into equal right and left halves
Median Sagittal Plane
In Sagittal plant:
Planes situated to one or the other side of
the median plane and parallel to it
para-median

Medial
Structure that lies farther away from the median plane than
another

Eversion
is composed of dense connective tissue containing many blood
vessels, lymphatic vessels, and nerves
Dermis
stratified epithelium whose cells become flattened as they mature and rise to the surface. On the palms of
the hands and the soles of the feet. It is extremely
thick, to withstand the wear and tear that occurs in these
regions.
Epidermis
The dermis of the skin
is connected to the underlying deep fascia or bones
Superficial fascia or subcutaneous tissue
4 appendages of the skin
- Nails
- hair follicles
- sebaceous glands
- sweat glands
The pull of the muscle also causes dimpling
of the skin surface
goose-flesh

is a membranous layer of connective tissue that invests the muscles and other deep structures
deep fascia
In the region of joints, the deep fascia may be considerably thickened to form restraining bands
retinacula
Their function is to hold underlying tendons in position or to serve as pulleys around which the tendons may move.
retinacula

chief muscle or member of a chief group of muscles
responsible for a particular movement
Prime mover
Any muscle that opposes the action of the
prime mover
Antagonist
contracts isometrically (i.e., contraction increases the tone but does not in itself produce movement) to stabilize the origin of the prime mover so that it can act efficiently
Fixator
To prevent unwanted
movements in an intermediate joint, groups of muscles
called (BLANK) contract and stabilize the intermediate
joints.
Synergist
Elaborate about Smooth Muscle
- long, spindle-shaped cells closely
arranged in bundles or sheets - provides the motive power for propelling the contents
through the lumen - causes
the ingested food to be thoroughly mixed with the digestive juices
Elaborate about cardiac muscle
- striated muscle fibers
- forms the myocardium
- arranged in whorls and spirals, and they have the property of spontaneous and
rhythmic contraction.
supplied by autonomic nerve fibers
that terminate in the nodes of the conducting system and
in the myocardium.
Cardiac muscle
The cardiac muscle receives its blood supply from what arteries
Coronary arteries
two or more bones come together
Joints
3 Types of joints
fibrous joints, cartilaginous joints, and synovial
joints.
Very little moment.
Example of this joint are:
- The sutures of the vault of the skull
- the inferior tibiofibular joints
Fibrous Joints
bones are united by a plate or a bar of hyaline cartilage.
-No movement is possible
primary cartilaginous joint
bones are united by a plate of fibrocartilage and the articular surfaces of the bones are covered by a thin layer of hyaline cartilage.
- small amount of movement is possilbe
secondary cartilaginous joint
example of fibrous joint
coronal suture of the skull
example of cartilaginous joint
joint between two lumbar verebral column
example of synovial joint
hip joint
found in some synovial joints lying
between the synovial membrane and the fibrous capsule
or bone.
Fatty pads
can be classified according to the arrangement of the articular surfaces and the types of movement
that are possible
Synovial joints
In plane joints, the apposed articular surfaces are flat or almost flat, and this permits the bones
to slide on one another.
plane joints
examples of plain joints
- sternoclavicular
- acromioclavicular joints
resemble the hinge on a door,
so that flexion and extension movements are possible
Hinge joints
examples of hinge joints
elbow, knee, and ankle joints

rotation is the only movement possible
Pivot joints

convex surfaces that articulate with two concave surfaces.
Condyloid joints

elliptical convex
articular surface fits into an elliptical concave articular
surface. Rotation is impossible
Ellipsoid joints

wrist joint
the articular surfaces are
reciprocally concavoconvex and resemble a saddle on
a horse’s back. permit flexion, extension,
abduction, adduction, and rotation.
Saddle joints
examples of Saddle joints
carpometacarpal joint of the
thumb
a ballshaped head of one bone fits into a socketlike concavity of another. permits free movements,
including flexion, extension, abduction, adduction,
medial rotation, lateral rotation, and circumduction.
Ball-and-socket joints
examples of Ball-and-socket joints
shoulder and hip joints
The stability of a joint depends on three main factors:
- shape of articular surfaces
- ligaments
- muscle tone
2 joints shows how bone shape plays an important
role in joint stability.
- hip joint
- ankle joint
prevent excessive movement in a joint
, but if the stress is continued for an excessively
long period, then fibrous ligaments stretch.
Fibrous ligaments
return to their original length
after stretching
Elastic ligaments
major factor controlling
stability
Muscle Tone
the sensation of pain in a joint is lost
syringomyelia
affects large synovial joints such
as the ankle, elbow, or wrist
Gonococcal arthritis
affects synovial joints and may start in the synovial membrane
or in the bone
tuberculous arthritis
- a cord or band of connective tissue uniting two structures. - composed of dense bundles of collagen fibers - composed of dense bundles of collagen fibers
ligament
A sensory nerve supplying a joint also supplies the muscles moving the joint and the skin overlying
the insertions of these muscles.
Hilton’s law
- lubricating device consisting of a closed fibrous
sac lined with a delicate smooth membrane. - found wherever tendons rub against bones, ligaments, or other tendons
Bursae
- tubular bursa that surrounds a tendon.
- occur where tendons pass under ligaments and retinacula and through osseofibrous tunnels.
Synovial Sheath
enables blood vessels to
enter the tendon along its course
mesotendon
when
the range of movement is extensive, the mesotendon disappears or remains in the form of narrow threads
vincula
reduce friction between the tendon and
its surrounding structures.
