Lecture 2: Intro To Anatomy Flashcards
Superficial
Near the body surface
The breast bone is superficial to the heart
Deep
Farther away from the body’s surface. The heart is deep to the chest bone
Proximal
Nearest to the attached limb
The elbow is proximal to the wrist - bc the elbow is closer to the shoulder which is the attachment point
The wrist is proximal to the fingers
Distal
Farther away from attachment of the limb
The elbow is distal to the shoulder
The wrist it’s distal to the elbow
Dorsum
The superior aspect of any part that protrudes anteriorly from the bod
- the tongue, penis, hands, and feet all have a dorsum (superior - top) surface.
- DORSUM DONOT touch the ground
Plantar
Is the sole of the foot
How could I describe the nipple to the belly button and opposite?
Medialinferior
Superiorlateral
Bilateral vs unilateral
Bilateral: having two of the same structure on both the right and the left side of the body.
- kidneys, hands, feet, eyes, ears…..
Unilateral: having only one on either the left side of the body or the right NOT both
- appendix, spleen….
Ipsilateral
Occurring in the same side of the body (either right or the left)
- right hand and right foot.
- left ear and left left eye
Contralateral
Occurring on the opposite side of the body
- the right hand and the left leg
- the left eye and the right ear
Flexion
Bending or decreasing
- above the knee flexion means to bend forward. Anterior movement
- bend at the hip, bend the bicep forward, bring the arm forward - below the knee is bending backward.
- flexion is done by bending the knee back or curling the toes back
Extension
Is straightening the joint
- straightening the knee out, fingers out, arm out…
Dorsiflexion
Flexion of the ankle joint by bringing the foot to the sky
“DOOR”siflexion bringing foot up to hold the door
Planarflexion
Flexion at the ankle to bring the heal off the ground
‘PLANT”arflexion lifting on toes to look at plants
Hyperextension
Extension of the limb beyond the normal limit
- this has to have work done to it in order to bend because we cannot physically do this alone
Abduction
Moving away from the median plane
Abducting the arm away
Adduction
Adding the limb back to the medial plane
Rotation
Turning around a body part around its axis
Medial rotation
Rotation to bring back to the medial plane
- You are looking left or right and you turn your head to look straight is an example of medial rotation
Lateral rotation
Moving your head to look left or right. Rotation away form the median plane
Circumspection
Is moving of the loving on all direction in a circle
- special sequence of abduction, adduction, extension, and flexion
“CIRCLE”
Lateral flexion
Special form of abduction for only the neck and trunk. Touching ear to shoulder
Pronation
Rotated the radius medially so the palm of the hand is facing down
- palm is facing posterior and the dorsum is facing anterior
Supination
Lateral movement of the radius so the palms are facing up
- the palms are now facing superior and the dorsum is facing posterior
Eversion
Moved the isle of the foot away from medial plane. Moves sole of foot to point outward
Inversion
Turning the sole of the foot to the median
Turning the sole of the foot “IN”version
Protrusion
Anterior movement
- protruding chin, lips, or tongue
Retrusion
Posterior movement
- pilling the tongue back in the mouth, moving the jaw back, pulling lip back in
Protraction
Anteriolateral movement
- moving shoulder blades forward
Retraction
Posteriomedial
- pulling shoulder back
Anatomical variation
All out structural differences that make us who we are
- some have the tendency to and wrist and some don’t
Tissue
recognizable collection of cells plus material (matrix) between cells that function as units
Tissue are thought of as fabrics use to construct organ systems
What are the four basic types of tissues
1 - epithelium
2 - connective tissue
3 - muscle tissue
4 - nervous tissue
Epithelium
Is the outer later that is used for protection, secretion, and absorption
- cells are tacked very tightly with little intercellular matrix fluid
- forms the linings and coverings of the bodies surface, cavities, organs, and major tissue glands
How are epithelium cells attached to underlying connective tissue
Basement membrane
Epithelium shapes?
Squamous, cuboidal, or columnar
Can be arranged in single or multilayers
