Match Each Gland To Its Function: Thyroid, Parathyroid, Hypo

Match Each Gland To Its Function Thyroid Parathyroid Hypothalamus

1. Match each gland to its function:

• Thyroid - Secretes calcitonin to lower blood calcium levels
• Parathyroid - Secretes hormone that raises calcium levels
• Hypothalamus - Secretes FSH (follicle-stimulating hormone) and LH (luteinizing hormone)
• Adrenal gland - Secretes a hormone that stimulates T cells of the immune system
• Pancreas - Secretes insulin and glucagon to regulate glucose levels

2. To determine if a skeleton is male or female, a forensic anthropologist evaluates several skeletal features that exhibit sexual dimorphism, as these characteristics differ between the sexes due to biological and hormonal influences. Key skeletal traits include the pelvis, skull, and overall robustness of bones.

Firstly, the pelvis is the most reliable indicator owing to its role in childbirth. The female pelvis tends to be broader, with a wider pelvic inlet and a more circular pelvic brim to facilitate childbirth. The pubic arch in females is more obtuse, typically exceeding 90 degrees, whereas in males, it is more acute (

Secondly, the skull showcases sexual dimorphism. Male skulls tend to be larger and more robust, with heavier brow ridges, a more prominent jawline, and larger mandibular angles. The forehead in males is typically more sloping, while females often have a more vertical forehead. The mastoid processes are more pronounced in males as well.

Thirdly, overall skeletal robustness can contribute. Males are generally more muscular, resulting in thicker, denser bones with more prominent muscle attachment sites. Females exhibit smoother, lighter bones that reflect less muscle mass.

By carefully examining these features and comparing them to established standards, forensic scientists can estimate the probable sex of the skeleton with reasonable accuracy. Combining pelvic examination with cranial and post-cranial analysis provides the most reliable assessment of biological sex.

Discussing the differences between general and special senses

Human sensory perception is categorized into general senses and special senses, each serving distinct functions in interpreting our environment. General senses include touch, pressure, temperature, pain, proprioception, and vibration, which are distributed throughout the body and mediated mainly by receptors in the skin, muscles, and joints. These senses provide continuous feedback about the body's internal and external environment, enabling us to perform everyday activities such as feeling textures, sensing pain, and maintaining posture.

Special senses, on the other hand, are limited to specific organs and include vision, hearing, taste, smell, and equilibrium. These senses involve highly specialized structures—like the eyes and ears—that detect specific stimuli and perform complex processing. For example, vision involves photoreceptors in the retina, while olfaction relies on receptors in the nasal cavity, and gustation on taste buds on the tongue.

Among the special senses, I believe vision is the most vital to human functioning. Vision provides the majority of our sensory input, allowing us to navigate our environment efficiently, recognize faces, read, and interpret visual cues that inform decision-making. It is essential for safety—detecting hazards and interpreting social signals—and for learning, as most educational material is presented visually. Loss of vision severely impairs independence and quality of life, underscoring its importance. While other senses like hearing and touch are critical, the capacity to see influences so many daily activities and survival functions that it arguably holds the greatest significance among the senses.

Matching parts of the cerebrum or cerebellum to their functions

• Parietal lobe - Processes information about touch and self-awareness
• Frontal lobe - Processes voluntary muscle movement, involved in memory
• Temporal lobe - Involved in processing auditory and olfactory information
• Occipital lobe - Processes visual information
• Cerebral cortex - Generates and understands speech and other sensory information
• Corpus callosum - Allows communication between the two cerebral hemispheres
• Thalamus - Relays information between the spinal cord and cerebrum
• Hypothalamus - Controls center for hunger, thirst, and body temperature
• Cerebellum - Controls balance, muscle movement, and coordination
• Brain stem - Controls reflexes and spontaneous functions

The structure-function relationships in the brain are crucial to understanding neural processing and behavior. The parietal lobes process sensory input related to touch, pressure, and self-awareness, integrating spatial information and proprioception essential for movement and coordination. The frontal lobes are associated with voluntary motor functions, executive functions like decision-making, problem-solving, and aspects of memory and language production. Temporal lobes specialize in processing auditory stimuli and olfactory signals, crucial for hearing and smell. Occipital lobes primarily handle visual information, enabling perception and interpretation of the visual world.

The cerebral cortex, the outermost layer of the cerebrum, is involved in complex functions such as speech, reasoning, and sensory integration. The corpus callosum facilitates communication between the two hemispheres, ensuring coordinated brain activity. The thalamus acts as a relay station, transmitting sensory signals to the appropriate cortical areas. The hypothalamus regulates vital functions like hunger, thirst, body temperature, and circadian rhythms, maintaining homeostasis. The cerebellum ensures smooth and coordinated muscle activity and balance, essential for movement accuracy. The brain stem manages vital spontaneous functions, including heartbeat, breathing, and reflexes necessary for survival.
