The greater occipital nerve is a spinal nerve, specifically the medial branch of the dorsal primary ramus of cervical spinal nerve 2. This nerve arises from between the first and second cervical vertebrae, along with the lesser occipital nerve. It ascends after emerging from below the suboccipital triangle beneath the obliquus capitis inferior muscle. It then passes through the semispinalis muscle before ascending to innervate the skin along the posterior part of the scalp to the vertex. It innervates the scalp at the top of the head, over the ear and over the parotid glands.
The lesser occipital nerve or small occipital nerve is a cutaneous spinal nerve arising between the second and third cervical vertebrae, along with the greater occipital nerve. It innervates the scalp in the lateral area of the head posterior to the ear.
The posterior tibial artery of the lower limb carries blood to the posterior compartment of the leg and plantar surface of the foot, from the popliteal artery via the tibial-fibular trunk. It is accompanied by a deep vein, the posterior tibial vein, along its course.
The anterior tibial artery of the leg carries blood to the anterior compartment of the leg and dorsal surface of the foot, from the popliteal artery.
The zygomaticotemporal nerve or zygomaticotemporal branch is a small nerve in the face. It is derived from the zygomatic nerve, a branch of the maxillary nerve. It runs along the lateral wall of the orbit in a groove in the zygomatic bone, receives a branch of communication from the lacrimal nerve, and passes through the zygomaticotemporal foramen in the zygomatic bone to enter the temporal fossa.
The posterior ethmoidal nerve is a branch of the nasociliary nerve.
The posterior ethmoidal artery is an artery of the head which supplies the nasal septum. It is smaller than the anterior ethmoidal artery.
The supratrochlear artery, one of the terminal branches of the ophthalmic artery, branches off where the ophthalmic artery travels posterior to the trochlea.
The digastric branch of facial nerve arises close to the stylomastoid foramen, and divides into several filaments, which supply the posterior belly of the Digastricus; one of these filaments joins the glossopharyngeal nerve.
In human neuroanatomy of the face, the stylohyoid branch of facial nerve frequently arises in conjunction with the digastric branch; it is long and slender, and enters the Stylohyoideus about its middle.
The aditus to mastoid antrum is a large irregular cavity that leads backward from the epitympanic recess into a considerable air space named the tympanic or mastoid antrum.
The medial tarsal arteries are two or three small branches which ramify on the medial border of the foot and join the medial malleolar network.
The anterior facial vein receives a branch of considerable size, the deep facial vein, from the pterygoid venous plexus.
While under the Trapezius, the medial branch of the posterior division of the third cervical nerve gives off a branch called the third occipital nerve, which pierces the Trapezius and ends in the skin of the lower part of the back of the head.
Tibial-fibular trunk is a segment of artery below the knee, distal to the origin of the anterior tibial artery off the popliteal artery, and proximal to the branch point of the posterior tibial artery and the fibular artery.
The dorsal digital arteries of foot are small arteries which supply the toes.
The proper plantar digital arteries are arteries of the foot.
The common plantar digital arteries are arteries of the foot.
The anterior median line is a sagittal line on the anterior of the head and torso running at midline.
Pump-handle is a movement of the ribs that results in a change in the anteroposterior diameter of the thorax.
