Morphometric Development of Medial Surface of Cerebrum in Fetal Cadavers.

Aim: To investigate the morphometric and morphological development of the medial surface of the cerebrum in 40 fetal cadavers without external anomalies and pathologies between the gestational ages of 22 and 40 weeks.

Material And Methods: In this study, we measured the height and width of the cerebral hemisphere, cingulate sulcus, marginal sulcus, sulcus of the corpus callosum, calcarine sulcus, parieto-occipital sulcus, and central sulcus in each hemisphere. We examined these measures between genders and sides and assessed how these parameters developed over the course of gestational age (measured in months).

Anatomical Variations of the Musculocutaneous Nerve in the Human Fetus.

Objectives: Knowing the motor branches and variations of the musculocutaneous nerve to the muscles along its course will facilitate the treatment of flexor spasticity and supracondylar fractures of the humerus in order to minimize nerve lesion. In fetal cadavers, the purpose of our study was to determine the number and course of the formation variations and motor branches of the musculocutaneous nerve. The significance of studying fetal nerve variations is due to injury to the brachial plexus roots during birth.

Innervation Patterns of the Psoas Major and Iliacus Muscles in Fetal Cadavers.

Aim: We aimed to investigate in detail the innervation patterns of the psoas major and iliacus in fetal cadavers.

Material And Methods: The innervation patterns of 94 psoas major and 94 iliacus belonging to 47 fetuses (28 males, 19 females) aged between the 18th-40th gestational weeks in the laboratory of the Department of Anatomy at the Faculty of Medicine were examined. The nerve branches innervating the psoas major and iliacus and the origin levels of these branches were determined.

An Investigation of the Morphometry and Localization of the Foramen Ovale and Rotundum in Asymptomatic Individuals and Patients with Trigeminal Neuralgia.

Aim: To compare the morphometric characteristics of the foramen ovale (FO) and foramen rotundum (FR), and their localization in the middle cranial fossa on the head and neck computed tomography images of patients with trigeminal neuralgia (TN) and asymptomatic individuals.

Material And Methods: The FO and FR length, width, and area parameters were examined in 158 asymptomatic individuals and 19 patients with TN. Their localization in the middle cranial fossa was determined according to the sagittal (y) axis passing through the middle of the dorsum sella and connecting the foremost point and the rearmost point of the skull and the transverse (x) axis passing through the middle of this axis.

The development of the medial longitudinal arch in the intrauterine period.

In this study, we aimed to reveal whether the medial longitudinal arch is formed in the intrauterine period and the structural features of the medial longitudinal arch. The study was conducted on 146 feet of 73 fetuses (38 male, 35 female) aged between 15 and 40 weeks of gestation. The fetuses were grouped by trimesters.

Anatomical variations of the extensor tendons of the fetal thumb.

Purpose: The extensor pollicis longus (EPL) and brevis (EPB) and abductor pollicis longus (APL) are muscles located in the posterior compartment of the forearm. These muscles allow the thumb to move independently from the other four fingers by attaching to the thumb separately. This study's goal was to investigate the tendon variations and insertions of these muscles.

Morphometric Development of the Mandible in Fetal Cadavers.

Purpose: The aim of this study is to present reliable data by measuring the morphometric properties of the mandible in the fetal period.

Methods: A study was performed on mandibles of 35 fetuses (18 male fetuses and 17 female fetuses), aged between 21 and 40 weeks of gestation. Fetuses were examined in 3 groups according to their developmental stages: 2nd trimester, 3rd trimester, and full-term.

A case with multiple accessory foramina of mandible in a fetus.

It is aimed to better recognize the mandibular variations by understanding the diversity and positions of accessory foramina better. Accessory formations on a full-term fetal mandible dissected for a mandibular study were examined under a microscope. To observe these formations more clearly, they were photographed with the help of a camera and microscope.

Morphometric development of the tongue in fetal cadavers.

Purpose: The tongue is a specific organ for the sense of taste. It consists of the striated muscle and mucous membrane. Furthermore, it helps the functions of speech, chewing, and swallowing.

Anatomical relation between sciatic nerve and piriformis muscle and its bifurcation level during fetal period in human.

Purpose: The aim of this study is to determine the morphometric development, location and variant formations of the sciatic nerve using anatomic dissection method during the fetal period.

Methods: Sciatic nerves of 200 human fetuses (103 males and 97 females) aged between 9 and 40 weeks of gestation were studied bilaterally. The bifurcation level of the sciatic nerve to its terminal branches was evaluated with respect to popliteal fossa.

Anatomy and variations of palmaris longus in fetuses.

The aim of this study was to assess the absence of the palmaris longus, the proportion of the lengths of tendon and muscle belly, the development of the tendon and the belly during the fetal period, look for any difference between sides and gender. Fifty-eight spontaneously aborted human fetuses (26 female, 32 male, 116 upper extremities) were studied. The presence or absence of the palmaris longus was determined.

Motor branching patterns of the ulnar nerve in the forearms of fetal cadavers.

Purpose: The aim of this study was to investigate the branches of the ulnar nerve given to forearm muscles [flexor carpi ulnaris (FCU) and flexor digitorum profundus (FDP)] and typing of ulnar nerve according to distribution of these branches to the muscles.

Methods: From the collection of Anatomy Department Laboratory, Faculty of Medicine, Suleyman Demirel University, 116 upper limbs of fetuses showing no external anomaly and aging between 12th and 40th weeks of pregnancy, were included in this study for anatomical dissection. Parameters about the branching of fetal ulnar nerve were set as follows: branch/branches to FCU muscle and branch/branches to FDP muscle.
