Summary
The head
Area of Science:
- Zoology
- Comparative Anatomy
Background:
- The Sulawesi Babirusa (Babyrousa celebensis) is a unique wild pig species.
- Its detailed muscular anatomy has not been previously described.
- Understanding its anatomy can provide insights into evolutionary relationships.
Purpose of the Study:
- To provide the first detailed description of the muscular anatomy of the Sulawesi Babirusa head.
- To compare the muscular anatomy of Babyrousa celebensis with that of the pig genus Sus.
Main Methods:
- Detailed dissection of the head musculature of the Sulawesi Babirusa.
- Comparative analysis with existing anatomical descriptions of the domestic pig (Sus scrofa domesticus).
Main Results:
- The overall muscular anatomy of Babyrousa celebensis is highly similar to the genus Sus.
- Specific differences were identified in the M. parietoauricularis, M. levator anguli oculi, M. palatinus, and Platysma pars zygomatica.
- These variations highlight unique adaptations in the Babirusa despite its evolutionary divergence.
Conclusions:
- The study establishes a baseline for the head musculature of Babyrousa celebensis.
- Despite significant geological separation, Babirusa shares fundamental muscular traits with pigs.
- Identified differences suggest specific evolutionary pathways and functional adaptations in Babirusa head anatomy.

01:14Muscles for Facial Expressions
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
01:20Muscles of the Eye
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and rotating...

01:19Muscles that Move the Head
The muscles that move the head are a dynamic and complex group of structures that work together to facilitate a wide range of head movements, including rotation, flexion, extension, and lateral bending.
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...

01:14Cranial Bones: Superior and Posterior View
The superior view of the cranium shows the frontal and paired parietal bones.
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...

01:22Sutures of the Skull
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:27Cranial Bones: Lateral View
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
