Anisocoria

Anisocoria

Anisocoria is a different pupil size between the left and right eye of a person. This does not always have to have an illness value, but if it occurs suddenly it can indicate an illness.

Hindbrain

Hindbrain

The hindbrain is part of the central nervous system and is assigned to the hindbrain, which also includes the medulla oblongata. The rear brain includes the pons (bridge) and the cerebellum (cerebellum). The cerebellum plays a big role

Cerebellar bridge angle

Cerebellar bridge angle

Cerebellar bridge angle (Angulus pontocerebellaris) is the name of a specific anatomical structure of the brain. It lies between the brain stem, cerebellum and temporal bone in the posterior fossa. Two important cranial nerves, the facial and nerve

Patellar tendon reflex

- your medical information portal. Here you will find information on the subject of the patellar tendon reflex explained to laymen.

Structure of the nervous system

Structure of the nervous system

The human nervous system consists of nerve tissue, which is primarily composed of nerve cells and glia. First, a distinction is made between a central nervous system, which is made up of the brain and spinal cord, and a peripheral nervous system

Hippocampus

Hippocampus

The name hippocampus comes from Latin and means seahorse. The hippocampus bears this name based on its seahorse-like shape. It shapes human memory by changing content from short-term to long-term memory

Small round muscle

Small round muscle

The small round muscle (M. teres minor) runs between the outer surface of the shoulder blade and the humerus and is responsible for the adduction and external rotation of the upper arm.

Deltoid

Deltoid

The deltoid muscle is similar in shape to the inverted Greek delta, which is how it gets its name. The deltoid muscle (Musculus deltoideus) becomes the most important lifter of the arm through the middle section coming from the shoulder blade.

callus

callus

Callus formation occurs during fracture healing. New, soft bone tissue is created, which is then converted into normal bone tissue in the further course.

Metatarsus

Metatarsus

The metatarsus consists of five metatarsal bones, which form various articulated connections to the adjacent bones. The metatarsus is used to adapt the foot to uneven ground and to maintain mobility. Common illnesses are

Juvenile bone cyst

Juvenile bone cyst

A bone cyst is a fluid-filled cavity in the bone. A distinction is made between a simple (juvenile) and aneurysmal bone cyst. The clinical picture of the juvenile bone cyst occurs mainly in children and adolescents

Aneurysmal bone cyst

Aneurysmal bone cyst

The aneurysmal bone cyst is a benign bone tumor. The blood-filled cyst located in the bone is divided into several individual cavities by septa. Usually the change is symptom-free, but it can

Costal arch

Costal arch

The costal arch is the cartilaginous connecting piece between the sternum and the ribs 8 to 10, which are too short to interact directly with the sternum. The costal arch therefore limits the chest from the front and below. As a result of bruises k

Biceps femoris

Biceps femoris

The two-headed thigh muscle lies on the back of the thigh and belongs to the flexor group. The function of the biceps femoris, two-headed thigh muscle, consists of flexing and external rotation of the lower leg in the knee joint and one

Iliotibial band

Iliotibial band

The iliotibial band is a layer of connective tissue that reinforces the fascia lata on the side of the thigh. It is therefore responsible for the tension banding of the thigh, i.e. for stabilizing the thighbone against lateral bending

Outer bands on the foot

Outer bands on the foot

The outer ligament on the foot actually consists of three ligaments, all of which originate from the outer ankle. The so-called talofibular ligament anterius is the thinnest ligament and is therefore much more often affected by ligament tears. A ligament tear or stretch

Anterior tibial muscle

Anterior tibial muscle

The anterior tibial muscle (M. tibialis anterior) is the antagonist to the M. gastrocnemius and flexes the foot in the ankle.

Muscle agonist-antagonist

Muscle agonist-antagonist

A healthy person has 656 muscles that perform different tasks on the extremities. A muscle pair, i.e. an agonist and an antagonist, perform movements in opposite directions - such as flexion and extension. So you will too

ossification

ossification

Ossification refers to the formation of boil. A distinction is made between the formation of the bone from connective tissue, which is known as desmal ossification, and chondral ossification, in which the bone is already formed from one

Trapezius muscle

Trapezius muscle

The hood muscle (M. trapezius) is a superficial muscle that extends across the back between the two shoulders, the neck and the 12th thoracic vertebra. Divided into three main parts, it can perform different functions, e.g.
