Starting at the front or anterior end, you find the labrum which is the upper lip. The cuff of cartilage increases the surface area of the shoulder joint, enabling the range of motion for the arm. Grasshopper Head (Figure 1) Label the following: Antennae Compound eyes Ocelli (or simple eyes) Mouth parts - Labrum (upper lip), mandibles (jaws), maxillae, and the labium (lower lip) External Grasshopper anatomy (Figure 2) Label the following: HEAD . Dissect the mouthparts and examine them more closely. The Malpighian tubules and hindgut perform these same functions for insects. The ‘upper lip’ of the insect mouth-parts: not a true appendage but a movable sclerite on the front of the head. Name given to a young insect which is markedly different from the adult: caterpillars and fly maggots are good examples. Each mouthpart is shown separately below with labels as follows: lr = labrum, md = mandibles, mx = maxillae, lb = labium, hp = hypopharynx (modified tongue-like region of the labium). Chewing & Biting Type: The basic and most primitive type of mouthparts present in grasshopper, cockroach and beetles. Find the outside most plate (like an upper lip) which is called the labrum, its opposite is the lower plate (lower lip) called the labium. 2. The current paper aims to review the anatomy and biomechanical function of the labrum and how they are affected by differing surgical techniques. Grasshoppers feed on plants. The mouthparts of grasshoppers, shown in Figure 37-4a, are modified for cutting and chewing leaves and blades of grass. The labrum and labium are mouthparts that function like upper and lower lips, respectively. They hold the food in position so that the sharp-edged mandibles can tear off edible bits.
