Lobes of the Cerebrum01:22

Lobes of the Cerebrum

4.7K
The cerebral cortex, a critical structure of the brain, is intricately divided into two hemispheres, each consisting of four distinct lobes: occipital, temporal, frontal, and parietal. These lobes function cooperatively to regulate various cognitive and sensory functions, forming the basis of our complex neural capabilities.
Frontal lobe
The frontal lobes, located behind the forehead, are the command center of our brain, controlling personality, intelligence, and voluntary muscle movements....

Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

2.3K
The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

Muscles of the Anterior Neck01:26

Muscles of the Anterior Neck

4.7K
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

Veins of Upper Limbs01:17

Veins of Upper Limbs

4.1K
The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...

Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

7.1K
The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Upper Respiratory Drugs: Decongestants01:27

Upper Respiratory Drugs: Decongestants

901
Decongestants are a class of medications used primarily to alleviate nasal congestion, a common symptom resulting from allergies, colds, sinusitis, and other upper respiratory tract infections. These drugs work by activating α-adrenergic receptors, constricting small blood vessels in the nasal membranes. This action results in the opening of clogged nasal passages, thereby facilitating sinus drainage and relieving congestion.
Most decongestants are readily available over-the-counter in...

Summary

Minimally invasive pulmonary segmentectomy offers effective lung cancer treatment while preserving lung tissue. This thoracoscopic approach enhances safety and recovery, minimizing hospital stays.

Area of Science:

  • Thoracic Surgery
  • Surgical Oncology
  • Minimally Invasive Procedures

Background:

  • Pulmonary segmentectomy is a minimally invasive surgical option for lung cancer.
  • It aims to preserve lung parenchyma and reduce patient morbidity.
  • Standardized techniques are crucial for successful outcomes.

Observation:

  • A fully thoracoscopic multiport approach is favored for its direct access and versatility.
  • This technique allows for straightforward dissection of segmental structures.
  • Adaptability for intraoperative findings, like margin assessment, is a key feature.

Findings:

  • Key elements include patient and trocar positioning, and standardized dissection.
  • Accurate division of the intersegmental plane is essential.
