Pseudopod (literally: "false foot")
Study the terminology!
segmented body
Anterior positioning refers to the front of the body, while posterior positioning refers to the back of the body. The key difference lies in their locations relative to the body's midline. Anterior structures are towards the front, while posterior structures are towards the back.
No, the right hand is contralateral to the right foot. Ipsilateral refers to structures on the same side of the body while contralateral refers to structures on the opposite side of the body.
The terms 'cranial' and 'caudal' are used when referring to structures along the longitudinal axis of the body. 'Cranial' refers to structures towards the head, while 'caudal' refers to structures towards the tail or feet.
In humans, the orientation terms "superior" and "inferior" have opposite meanings, with "superior" referring to structures located toward the head or upper part of the body, while "inferior" refers to structures located toward the feet or lower part. Additionally, "anterior" and "posterior" are opposites, with "anterior" indicating the front of the body and "posterior" indicating the back. Another pair is "medial," which refers to structures closer to the midline of the body, and "lateral," which refers to structures farther from the midline.
No, the eyes are lateral and superior to the mouth. The term "medial" refers to structures closer to the midline of the body, while "superficial" refers to structures closer to the surface of the body.
The opposite of ipsilateral is contralateral, which refers to structures or functions on opposite sides of the body or brain.
Anatomical lateral refers to the side of the body furthest from the midline, while medial refers to the side of the body closest to the midline. Lateral structures are further away from the center of the body, while medial structures are closer to the center.
Your anterior is the front and the posterior is the back.
The opposite of peripheral in human anatomy is central. Peripheral typically refers to areas away from the center of the body, while central refers to structures located at or near the center of the body.
Amoebas move by using structures called pseudopods, which are temporary protrusions of their cell membrane that form in the direction they want to move. They extend and contract these pseudopods to push themselves forward in a process known as amoeboid movement.
Some amoebas are parasites, damaging the human body.
