It extends from the eyebrows to the superior nuchal lines and laterally to the superior temporal line.
Skin, connective tissue, aponeurosis, loose areolar tissue, and pericranium.
It binds blood vessels, preventing retraction and causing profuse bleeding when injured.
It connects the occipitofrontalis muscle and maintains tension, preventing wounds from gaping.
The loose areolar tissue layer where blood and pus can collect, leading to potential intracranial infection.
It can lead to a black eye due to tracking into the eyelids.
A collection of blood in the subaponeurotic space that can occur after cranial injury.
Supratrochlear, supraorbital, superficial temporal, posterior auricular, and occipital arteries.
They accompany the arteries and communicate with the facial vein and dural venous sinuses.
Anterior scalp drains into preauricular nodes; posterior scalp drains into posterior auricular and occipital nodes.
The area between the superior temporal line and zygomatic arch.
Skin, connective tissue, extension of epicranial aponeurosis, temporal fascia, temporalis muscle, and pericranium.
It is the thickest fascia in the body and serves as a graft in tympanoplasty.
It is thick, elastic, vascular, and contains numerous sweat and sebaceous glands.
They regulate orifice openings and produce various facial expressions.
It closes the eyelids tightly and gently, protecting the eye.
It produces vertical wrinkles on the forehead by dragging the eyebrow downwards.
It can lead to ectropion, causing tears to spill onto the cheek.
They develop from the mesoderm of the 2nd pharyngeal arch.
It extends from the eyebrows to the superior nuchal lines and superior temporal line.
Skin, connective tissue, aponeurosis, loose areolar tissue, pericranium.
Torn blood vessels cannot retract, leading to profuse bleeding.
It maintains tension and prevents wounds from gaping unless cut transversely.
The loose areolar tissue layer where blood and pus can collect, risking infection.
It can lead to a black eye due to tracking into the eyelids.
A collection of blood in the subaponeurotic space that can cause cerebral compression.
Veins connecting scalp veins to intracranial dural venous sinuses.
Supplied by supratrochlear, supraorbital, superficial temporal, posterior auricular, and occipital arteries.
Wounds bleed profusely but heal quickly due to rich vascularity.
Anterior scalp drains into preauricular nodes; posterior drains into posterior auricular and occipital nodes.
The area between the superior temporal line and zygomatic arch.
Skin, connective tissue, extension of epicranial aponeurosis, temporal fascia, temporalis muscle, pericranium.
It is the thickest fascia in the body and forms a roof over the temporal fossa.
Thick, elastic, very vascular, with numerous sweat and sebaceous glands.
They regulate orifice openings and produce facial expressions.
It closes the eye tightly and gently, protecting it from light and dust.
It produces vertical wrinkles on the forehead by dragging the eyebrow down.
It can lead to ectropion, causing tears to spill onto the cheek.
They develop from the mesoderm of the 2nd pharyngeal arch.
It aids in suckling and provides rounded contour to cheeks.
