Introduction To Clinically Oriented Gross Anatomy Flashcards
The study of the 💡structure of body parts and their 💡relationship to one another.
To 💡dissect, 💡cut apart, and 💡separate
ANATOMY
All structures in 💡one part of the body. (e.g. pelvic, abdomen)
Regional Anatomy
Study of internal structures as they related to the 💡overlying skin
Surface Anatomy
Gross anatomy of the body studied by 💡system (cardiovascular, nervous, skeletal, muscular
Systemic Anatomy
WAYS OF EXAMINING THE INTERNAL STRUCTURE
SURFACE ANATOMY
ANATOMICAL IMAGING
Study of the cell
Cytology
Study of the tissues
Histology
💡DEVELOPMENTAL ANATOMY
Study of development changes of the body before birth
Embryology
Composed of 💡bone, cartilage, and ligament
● 💡Protects and 💡supports body organs
● Provides the 💡framework for muscles
● Site of 💡blood cell formation
● Stores minerals like 💡calcium and 💡phosphorus
Skeletal system
Forms the 💡external body covering
● Composed of the 💡skin, sweat glands, oil glands, hair,
and nails
● 💡Protects deep tissues from injury and synthesizes
💡vitamin D
● Regulate the temperature and prevent water loss
● First line of defense
Integumentary system
Composed of 💡muscles and tendons ● Allows 💡manipulation of the environment, locomotion, and facial expression ● Maintains 💡posture ● Produces 💡heat through shivering
Muscular system
Composed of the 💡brain, spinal cord & nerves
● 💡Fast-acting control system of the body
● Detect 💡sensation and 💡control movements, physiological processes, and intellect
● Responds to 💡stimuli by activating muscles & glands
Nervous system
Composed of the 💡heart and blood vessels
● The 💡heart pumps blood
● Blood vessels 💡transport blood throughout the body
● 💡Transport nutrients, waste products, gases, and
hormones throughout the body
Cardiovascular system
Composed of 💡red bone marrow, thymus, spleen, lymph nodes, and lymphatic vessels
● Picks up 💡fluid leaked from blood vessels and returns it to blood
● 💡Disposes of debris in the lymphatic stream
● Houses 💡white blood cells involved with 💡immunity
● Removes 💡foreign substances from the blood and lymph
● Maintain 💡tissue fluid balance, and absorb fat from the digestive tract
Lymphatic system
Composed of the 💡nasal cavity, pharynx, trachea, bronchi, and lungs
● Keeps blood supplied with 💡oxygen and removes 💡carbon dioxide between blood and air
● Regulate the 💡blood pH
Respiratory system
Composed of the 💡oral cavity, esophagus, stomach, small intestine, large intestine, rectum, anus, liver, and pancreas
● 💡Breaks down food into absorbable units that enter the blood
● Eliminates 💡indigestible foodstuff as feces
Digestive system
Composed of 💡kidneys, ureters, urinary bladder, and urethra
● Eliminates 💡nitrogenous wastes from the body
● 💡Regulates water, electrolyte, and pH balance of the
bloo
Urinary system
Composed of 💡prostate gland, penis, testes, scrotum, and ductus deferens
● Main function is the 💡production of offspring
● Testes produce 💡sperm and 💡male sex hormones
● Ducts and glands 💡deliver sperm to the female
reproductive tract
Male reproductive system
Composed of 💡mammary glands, ovaries, uterine tubes, uterus, and vagina
● Main function is the 💡production of offspring
● Ovaries produce 💡eggs and 💡female sex hormones
● Remaining structures serve as 💡sites for fertilization and
💡development of the fetus
● Mammary glands produce milk to nourish the newborn
Female reproductive system
A common visual reference point
● Person stands erect with feet together and eyes
forward
● Palms face anteriorly with the thumbs pointed away
from the body
Anatomical Position
💡Toward and 💡away from the head, respectively
● The head is superior to the abdomen
● The navel is inferior to the chin
Superior and Inferior
💡Toward the front and 💡back of the body, respectively
● The breastbone is anterior to the spine.
● The heart is posterior to the breastbone.
Anterior and Posterior
💡Toward the midline, 💡away from the midline, and 💡between a more medial and lateral structure, respectively
● The heart is medial to the arm
● The arms are lateral to the chest
● The collarbone is intermediate between breastbone
and shoulder
Medial, Lateral, and Intermediate
💡Closer to and 💡farther from the origin of the body, respectively
● The elbow is proximal to the wrist
● The knee is distal to the thigh
Proximal and Distal
💡Toward and 💡away from the 💡body surface, respectively
● The skin is superficial to the skeletal muscles.
● The lungs are deep to the skin.
Superficial and Deep
Head, neck, and trunk
Axial
Appendages or limb
Appendicular
💡Divides the body into 💡right and 💡left parts
Sagittal
💡Sagittal plane that lies on the midline.
Midsagittal
💡Divides the body into 💡anterior and 💡posterior parts
Frontal or Coronal
💡Divides the body into 💡superior and 💡inferior parts.
Transverse or Horizontal (cross section)
Cuts made 💡diagonally
Oblique section
Movement that 💡decreases the angle movement of the joint
Flexion (Bend/Flex)
💡Bending of the neck or body toward the 💡right or 💡left side.
Lateral Flexion
Movement of the foot toward the 💡plantar surface (sole of the foot) as we are 💡standing on the toes.
Plantar Flexion
Movement of the foot 💡toward the shin, as we walk on the 💡heels.
Dorsiflexion
Movement that 💡increases the angle movement of the joint.
Extension (Straighten/Extend)
💡Abnormal or excessive extension of a joint 💡beyond its normal range of motion, thus resulting in injury.
Hyperextension
Types of joints where flexion and extension movements take place:
● Hinge – Ex. Elbow and Knee
● Ball and Socket - Ex. Shoulder
● Saddle - Ex. MCP joint of the thumb
● Condyloid - Ex. Hand MCP joints
💡UP AND DOWN movements that occur about a transverse axis through a joint
SAGITTAL PLANE
Moving the body part 💡away or 💡towards an 💡imaginary center line.
FRONTAL PLANE
(to take away)- moving the body part 💡away from the midline.
Abduction
(to bring together)- moving it 💡towards the midline.
Adduction
Occurs about a 💡longitudinal (vertical) axis 💡passing through a joint and through the length of the bone distal to it.
Rotation
