Skin and Fascia Flashcards
The body lies on its back
Supine position
The body lies on its face
Prone position
The body lies on its side right or left
Lateral decubitus position
The body les
on its back with flexion of hip and knee and abduction of hip joints
Lithotomy position
It is the vertical plane which passes the middle line of the body dividing it longitudinally into
Median plane (Sagittal ):
It is a plane parallel to and nearby the median plane.
Paramedian plane
It is the plane which cuts oy body vertically into an anterior part towards the front of the body
and A posterior part towards the back.
Coronal (Frontal) plane
It is the transverse plane runs horizontally cutting the body into an upper
(superior) and lower (inferior) parts
Horizontal plane
In front of / nearer to the front of the body
Anterior (Ventral)
Behind / nearer to the back of the body
Posterior (Dorsal)
Nearer to the upper end of the body
Superior (upper o cranial)
Nearer to the lower end of the body
Inferior (lower or caudal)
exactly in the middle line or median plane.
Median
nearer to the median plane.
Medial
away from the median plane.
Lateral
nearer to the root of the limb.
Proximal
away from the root of the limb.
Distal
towards the skin or the surface of the body.
Superficial
further away from the skin or the surface of the body
Deep
inside the organ or the body
Internal (inner)
near or on the surface of the organ, or body.
External (outer)
The skin consists of?
1- Dermis
2- Epidermis
Skin appendages?
1- hairs (Primary and Permanent)
2- Nails
3- Sebaceous glands
4- Sweat glands
Skin pigments
1- melanin
2- melanoid
3- Carotenes
4- Oxyhaemoglobin
5- Reduced hemoglobin
Functions of the superficial fascia?
- It prevents heat loss from the body, so it acts as thermal insulator (due to the presence of fat).
- It acts as a medium conducting the cutaneous nerves, blood vessels and lymphatics which
supply the skin - It contains skin muscles, as in face (muscles of expression), in the neck (platysma) and in the
scrotum (dartos muscle). - It contains special types of glands as mammary glands, sweat glands, and superficial lymph
nodes. - It softens and smoothens the surface of the body.
- It facilitates the movement of skin over the underlying structures.
Deep fascia Parts and Functions?
- Formation of broad sheets
- Formation of intermuscular septa and interosseous membranes
- Formation of retinacula
- Formation of palmar aponeurosis (in palm) and plantar aponeurosis (in sole)
- Formation of sheaths around big blood vessels, e.g.:
