Which bones make up the pectoral girdle?

A. Touch: Touch is a general sense detected by mechanoreceptors distributed throughout the body. It provides information about pressure, vibration, and texture, and does not require specialized organs.

B. Smell: Smell is a special sense mediated by olfactory receptors in the nasal cavity, requiring a specialized organ for detection.

C. Hearing: Hearing is a special sense detected by the cochlea in the inner ear, which is specialized for auditory perception.

D. Vision: Vision is a special sense mediated by photoreceptors in the retina of the eyes, requiring a highly specialized organ.

A. Provide structural support to the body: Structural support is mainly provided by the skeletal system and connective tissues, not the nervous system.

B. Produce hormones for growth and development: Hormone production is the role of the endocrine system; the nervous system may influence hormone release but does not directly produce them.

C. Transmit signals between different parts of the body: The nervous system communicates via electrical and chemical signals between the brain, spinal cord, and peripheral organs, coordinating responses to stimuli and maintaining homeostasis.

D. Regulate the body's temperature: Temperature regulation is managed primarily by the hypothalamus and autonomic responses, with the nervous system playing a coordinating role rather than being the primary regulator.
