Example Question #51 : Human Anatomy And Physiology
Muscles that oppose the action of another muscle are known as what?
Agonists
Opposers
Synergists
Prime movers
Antagonists
Antagonists
Muscles often occur in pairs called antagonistic pairs. An antagonistic pair consists of an antagonist and an agonist muscle. As one muscle contracts, the other relaxes. An example of an antagonistic pair is the biceps and triceps. To contract the biceps the biceps contracts and the triceps relaxes allowing for the lifting of the lower arm.
Example Question #52 : Human Anatomy And Physiology
Which is not a type of epithelia found in the human body?
Simple columnar
Pseudostratified cuboidal
Simple cuboidal
Pseudostratified columnar
Stratified cuboidal
Pseudostratified cuboidal
Simple cuboidal cells can be found on the surface of ovaries, simple columnar epithelium can be found lining many digestive tract organs, pseudostratified columnar are found in the trachea and aid with secretion and absorption, and stratified cuboidal protect ducts of various glands.
Example Question #53 : Human Anatomy And Physiology
To which region of the body does the term "clavicular" refer?
Arm
Finger
Collar bone
Neck
Collar bone
The clavicle is another term for the collar bone. In contrast, the term "brachial" refers to the arm, specifically the upper arm. The term "digital" refers to the fingers and toes, or the digits of the extremities. Lastly, the term "cervical" refers to the neck (either the neck region on our bodies, or the neck of organs, such as the female uterus).
Example Question #54 : Human Anatomy And Physiology
Which of the following groups of muscles in the leg allows a person to stand on their toes?
Plantarflexors
Inverters
Everters
Abductors
Dorsiflexors
Plantarflexors
Plantar flexion is the movement where the angle between the sole of the foot and the back of the leg decreases. Plantar flexors are part of the posterior compartment of the lower leg, and consist of flexor hallucis longus and flexor digitorum. These muscles not only work in plantar flexion but also flex the phalanges of the foot (toes).
Abduction is a movement where structures increase their distance to the midline.
Dorsiflexion is a movement where the toes are brought closer to the shin.
Eversion is the movement of the sole of the foot away from the median plane; inversion is the movement of the sole towards the median plane.
Example Question #51 : Introductory Concepts
Which is not one of the four main tissue types?
epithelial tissue
osseous tissue
neural tissue
connective tissue
osseous tissue
Osseous tissue, also known as bone tissue, is a type of connective tissue.
