Which part of the skeleton keeps the body upright?
vertebral column
The vertebral column holds the body upright. Movement – muscles are attached to bones, which are jointed. When the muscles contract the bones move. Blood production – red blood cells (to carry oxygen) and white blood cells (to protect against infection) are produced in the bone marrow of some bones.
What is the posterior part of the body?
Posterior or dorsal – back (example, the shoulder blades are located on the posterior side of the body). Medial – toward the midline of the body (example, the middle toe is located at the medial side of the foot).
What is the vertical section through the body?
coronal plane: Any vertical plane that divides the body into anterior and posterior (belly and back) sections. transverse plane: Any plane that divides the body into superior and inferior parts, roughly perpendicular to the spine. sagittal plane: Any imaginary plane parallel to the median plane.
When a person is standing upright in the anatomical position?
Standard Anatomical Position in Humans In this position, a person is standing upright with the lower limbs together or slightly apart, feet flat on the floor and facing forward, upper limbs at the sides with the palms facing forward and thumbs pointing away from the body, and head and eyes directed straight ahead.
What organs do your skull and ribs protect?
Protects and supports organs: Your skull shields your brain, your ribs protect your heart and lungs, and your backbone protects your spine.
Who has more bones male or female?
Males have larger skeletal size and bone mass than females, despite comparable body size.
What is the cephalic region of the body?
head
The cephalic region (head) or cranial region (skull) is at the top of the body and visible from the front and rear. The cervical region (neck) starts below the head, ends at the thorax, and is visible from the front and rear from below the head to the shoulders.
What organs are in the thoracic cavity?
[2] The thoracic cavity contains organs and tissues that function in the respiratory (lungs, bronchi, trachea, pleura), cardiovascular (heart, pericardium, great vessels, lymphatics), nervous (vagus nerve, sympathetic chain, phrenic nerve, recurrent laryngeal nerve), immune (thymus) and digestive (esophagus) systems.
What is anatomical body position?
Anatomical position: The position with the body erect with the arms at the sides and the palms forward. Anatomic terms such as anterior and posterior, medial and lateral, abduction and adduction, and so on apply to the body when it is in the anatomical position.
What are the 4 body positions?
The four main anatomical positions are: supine, prone, right lateral recumbent, and left lateral recumbent. Each position is used in different medical circumstances.
How are the locations of organs related to one another?
Directional orientation is another anatomical tool used to describe how parts of the body are related to one another. Each organ system spans large regions of the human body. It is helpful, therefore, to establish reference planes and directions that can help us describe specific locations of structures as we discuss them.
Where are the organs located on the head?
The head, or the spherical body part that contains the brain and rests at the top of the human body, has quite a few individual organs and body parts on it. (It should quickly be mentioned that hair occupies the space on top of the head, and the ears, the organs responsible for hearing, are located on either side of the head.)
What makes up the organ system in the human body?
What is an Organ? An organ is made up of the same type of tissues, which are well-organized to perform specific functions in all living things, including plants, animals, birds, insects, reptiles, mammals and humans. Organs collectively form organ systems. These organs are macroscopic in structure. The brain, heart, lungs, liver, kidneys are
Which is the largest internal organ in the human body?
Therefore, it is called the largest external organ of the human body. The liver is the largest internal organ in the human body, which weighs between 1.3 to 1.5 kg. The liver is located in the upper right portion of the abdomen and is the organ found only among the vertebrates.
