Which of the following receptors does not span the cell membrane 7 times
- A. beta-Adrenergic receptor
- B. Rhodopsin
- C. 5-HTic receptor
- D. Mineralocorticoid receptor
Correct Answer: D
Rationale: The mineralocorticoid receptor is an intracellular receptor that does not span the cell membrane. It belongs to the steroid hormone receptor family and acts as a transcription factor after binding to its ligand. In contrast, beta-adrenergic receptors, rhodopsin, 5-HTic receptors, and LH receptors are G-protein-coupled receptors (GPCRs) that span the membrane seven times.

Apraxia involves an inability to undertake learned and purposeful activities such as dressing, cooking etc., and means that sufferers must rely increasingly on caregivers to help with these activities. Limb apraxia is a common symptom of left hemisphere damage and consists of a deficit in performing gestures to verbal command or imitation. One form of rehabilitation training for limb apraxia is:
- A. Gestural training.
- B. Mime training.
- C. Motor training.
- D. Replication training.
Correct Answer: A
Rationale: Gestural training is a rehabilitation technique used to improve limb apraxia, a condition characterized by difficulty in performing purposeful movements. This training involves teaching individuals to recognize and execute appropriate gestures and postures, enhancing their ability to perform daily activities. By focusing on the coordination of movements and the context in which they are used, gestural training helps individuals regain functional independence and reduce reliance on caregivers.

The use of segments as a developmental strategy in vertebrates is evident in:
- A. the endoderm
- B. the axial skeleton, only
- C. the hindbrain, only
- D. both the axial skeleton and the hindbrain
Correct Answer: D
Rationale: Segmentation is a key developmental strategy in vertebrates, evident in structures like the axial skeleton (vertebrae) and the hindbrain (rhombomeres). This segmentation allows for the organized development of complex body plans and functional specialization along the antero-posterior axis.
