What are the key differences between the dorsal and ventral sides of an organism's body?
The dorsal side of an organism's body is typically the back side, while the ventral side is the front side. The key differences between the two sides include the location of certain structures like the spine and organs, as well as the types of appendages or limbs that may be present. The dorsal side is usually more protected and may have features like a backbone, while the ventral side is often more exposed and may contain vital organs.
What is the ventrum that a baby spider monkey clings to?
Anatomically, the ventrum is a location, the underbelly area on the ventral abdomen.
Difference between the upper and lower surfaces of the leaf?
Upper part darker, can see venation more clearly. Upper part (ventral) originates from xylem. Lower part (dorsal) originates from phloem. Do not confuse with other denominations of dorsal/ventral.
Where do the small nerves go when they branch from a ganglion of the ventral nerve cord on an earthworm?
The ventral nerve cord runs throughout an earthworm's body. When they start to branch from ganglion the nerve cords are still present throughout the segments.
What features does an arthropod have?
Members of phylum Arthropoda have segmented bodies, external skeletons, jointed appendages; have rigid body structures made mostly of bio-mineralized alpha-chitin. They must shed their exoskeleton in order to grow. They have repeated body segments with leg or appendage pairs, ventral nerve cords with paired ganglia in each segment. They are bilaterally symmetrical with compound eyes and an internal body cavity with an open circulatory system.
In Cockroach ventral nerve cord is present in what?
In cockroaches, the ventral nerve cord is part of the central nervous system, running along the underside of the body. It consists of a chain of segmented ganglia, which are clusters of nerve cells that control various bodily functions and movement. This structure is crucial for coordinating locomotion and processing sensory information. The ventral nerve cord connects to peripheral nerves that extend to different body segments.
What are five characteristics that identify arthropods?
Members of phylum Arthropoda have segmented bodies, external skeletons, jointed appendages; have rigid body structures made mostly of bio-mineralized alpha-chitin. They must shed their exoskeleton in order to grow. They have repeated body segments with leg or appendage pairs, ventral nerve cords with paired ganglia in each segment. They are bilaterally symmetrical with compound eyes and an internal body cavity with an open circulatory system.
What is the function of the ventral surfaceof a worm?
The ventral surface of a worm is the underside that typically faces the substrate it moves on. It plays a crucial role in locomotion by allowing the worm to anchor itself and push against the ground as it contracts and expands its body segments. This surface is often equipped with setae, small bristle-like structures, which aid in gripping the soil and enhancing movement. Additionally, the ventral surface may help with moisture absorption and protection from environmental factors.
What is the meaning of sternum?
A plate of cartilage, or a series of bony or cartilaginous plates or segments, in the median line of the pectoral skeleton of most vertebrates above fishes; the breastbone., The ventral part of any one of the somites of an arthropod.
What are the characteristic of the arthropods?
The Characteristics of Arthropods are : 1) Segmented body plan 2) Exoskeleton composed of chitin 3) Paired jointed appendages on variable number of segments 4) Dorsal heart with paired ostia (openings) 5) Hemocoelic body cavity (open circulatory system) 6) Nervous system comprised of a dorsal brain and ventral nerve chord
Are the ventral nerve cord and ventral blood vessel connected?
no
Is the naval of a killer whale a dorsal or ventral?
