Overview of Pancreas Anatomy The pancreas is a specialized organ that plays a crucial role in both digestion and hormone regulation.[1] It functions as an exocrine gland by releasing digestive juices and as an endocrine gland by producing essential hormones, such as insulin.[1][2] Pancreas anatomy is divided into four parts, with the uncinate process often … Read more
Overview of Neck Muscle Anatomy The neck muscle anatomy contains several muscles that help move the head in different directions.[1] These muscles are grouped based on their location in the neck: the front (anterior), side (lateral), and back (posterior) areas.[1] Each group of muscles has specific roles depending on where they are and how deep … Read more
Overview of Thyroid Anatomy The thyroid gland is a small, butterfly-shaped organ in the front of the neck.[1] It sits in the middle, just over the windpipe (trachea), and stretches from the C5 to T1 vertebrae in the spine.[1] This gland makes important hormones—thyroid hormones (T3 and T4) and calcitonin.[2] These helps control how the … Read more
Overview of Brain Anatomy The brain is a part of the control center of your body. It manages everything from your thoughts and emotions to your movements and memories. It also controls functions like breathing, heartbeat, and body temperature, running without you even noticing. Every part of who you are—your personality, reactions, and decisions—starts in … Read more
Overview of Brainstem Anatomy The brainstem is a small yet vital part of the brain. It is located at its base and connects the cerebrum (the largest part of the brain) to the spinal cord.[1] The brainstem anatomy consists of three main structures: the midbrain, the pons, and the medulla oblongata.[1] The thalamus is in … Read more
Overview of Midbrain Anatomy The midbrain, also known as the mesencephalon, is the topmost part of the brainstem.[1][2] It serves as a bridge between the cerebrum and diencephalon above and the pons below.[1] Despite of being 1.5-2 cm, it plays a vital role in several important functions, including vision, hearing, body movement, alertness, sleep cycles, … Read more
Overview of Cerebrum Anatomy The cerebrum, also known as the telencephalon or forebrain, is the largest and most superior part of the human brain.[1] It plays a central role in voluntary movement, thinking, learning, emotions, and memory.[2][1] Structurally, cerebrum anatomy is divided into two C-shaped hemispheres—left and right—separated by a deep groove called the longitudinal … Read more
Overview of Cerebellum Anatomy The cerebellum is located at the back of your head, just beneath the larger cerebral hemispheres.[1] It is protected above by a tough membrane called the tentorium cerebelli.[1] While the cerebellum doesn’t start muscle movements, it plays a key role in refining them. It helps you walk smoothly, stay balanced, and … Read more
Overview of Basal Ganglia Anatomy The basal ganglia, also known as the basal nuclei, are a group of deep brain structures located in the lower part of the forebrain, near the midbrain.[1][4] These structures are present in all vertebrates and play an important role in how the brain controls movement and behavior.[1][3] In humans, the … Read more
Overview of Lobes of the Brain The brain, along with the spinal cord, forms the central nervous system (CNS), which controls most body activities.[1] It is the most intricate organ, made up of many parts that work together to manage everything from basic survival functions to complex thinking.[1] The brain has three main sections: the … Read more
